Thank you for your purchase of the Canon Digital Camera.
This README file contains some information which may be helpful 
in diagnosing problems with the Canon Digital Camera TWAIN driver
or the Canon digital cameras. 

A NOTE ABOUT TWAIN:
Since the TWAIN standard is being updated on a regular basis, and
software application companies try to address these changes, you
may occasionally experience some minor problems caused by
applications that are not fully TWAIN compliant.  Canon works
closely with software manufacturers on compatibility issues to
ensure user's a trouble-free experience.

5. Un-Installing Canon Digital Camera TWAIN driver



1.  General Notes
=================
(1)  Disk space usage

     The TWAIN driver may create several temporary files on your 
     hard disk. These files are erased when the TWAIN driver is closed. 
     If your system ever crashes for any reason while the TWAIN driver 
     is in use, the files will be left on the hard disk. Each time TWAIN 
     driver starts, it will look for and erase such files.

(2)  16-bit vs. 32-bit TWAIN

     The Canon Digital Camera TWAIN driver is fully 32-bit. If your application
     allows selection of multiple TWAIN data source managers, take
     care to select "TWAIN_32".


2.  Windows 95 Specific Notes
=============================

(1)  If you are using the Microsoft Plus! add-on package for
     Windows 95, you may experience some unusual visual behavior of
     the main window of the Canon Digital Camera TWAIN driver while dragging
     or re-sizing it. This is harmless and it is done to maximize
     speed and to minimize re-drawing of the window. The window will
     re-draw completely once the drag/re-size operation is completed.
     Nevertheless, you may want to disable this feature by unchecking
     the appropriate checkbox located in the "Visual settings"
     options group of the Display Properties dialog.


3.  Windows NT Specific Notes
=============================

(1)  NTFS (NT File System) not supported on PCMCIA card installed in 
     camera.  PCMCIA card must be formatted with the FAT File System
     before camera will recognize it.

(2)  Removing a PCMCIA card from the card reader when system is running
     results in system lockup.  Be sure that Windows NT is completely
     shut down before removing or inserting a PCMCIA card.
	
(3)  Not all PC Card Readers have Windows NT 4.0 support. Check with 
     your PC Card vendor for details.

(4)  You may experience some unusual visual behavior of the main
     window of the Canon Digital Camera TWAIN driver while dragging or
     re-sizing.
     This is harmless and it is done to maximize speed and to minimize
     re-drawing of the window. The window will re-draw completely once
     the drag/re-size operation is completed.
     Nevertheless, you may want to disable this feature by unchecking
     the appropriate checkbox located in the "Visual settings"
     options group of the Display Properties dialog.


4.  Application Specific Notes
==============================

We have tried to ensure that the TWAIN driver works with most TWAIN-
compliant applications and machine configurations. However, we have
discovered the incompatibilities and problems listed below. In many
cases more recent versions of the applications solve the problems.

(1)  256 color video drivers

     Some applications such as Adobe PhotoShop and Micrografx Picture
     Publisher do not manage palettes correctly and may cause corruption
     of thumbnails displayed by the TWAIN driver. This does not affect
     the actual data, only the way it is displayed on the screen.
     Fix/workaround: contact vendor for new version of the software,
     or increase number of colors displayed.

(2)  keyboard shortcuts

     Some applications such as Adobe PhotoDeluxe, Ulead iPhotoExpress,
     Ulead PhotoImpact, Ulead ImageEditor, Micrografx Picture Publisher,
     and Microsoft Picture-It! may cause the TWAIN driver to not be able
     to properly respond to keyboard shortcuts.
     Fix/workaround: contact vendor for new version of the software.

(3)  Accessing TWAIN driver twice from same application

     Some applications such as Paint Shop Pro and Adobe PageMaker do not
     handle this situation correctly and cause the application or the TWAIN
     driver to crash.
     Fix/workaround: contact vendor for new version of the software,
     or avoid launching the TWAIN driver twice from the same application.

(4)  System hangs after acquiring an image

     Wang Imaging applet that ships with some versions of Windows 95
     and Windows NT hangs after acquiring an image. Newer version of the
     applet fixes this problem.

(5)  Removing PC card while accessing Canon Digital Camera images on it

     Some PC card drives may cause the system to hang if the PC card
     is removed while the Canon Digital Camera TWAIN driver has open image
     files on it.

(6)  PhotoAccess does not work with Canon Digital Camera TWAIN driver

     Older versions of PhotoAccess have a bug which cause the TWAIN
     negotiation to fail.
     Fix/workaround: contact vendor for new version of the software.

(7)  Some applications create extra files on PC cards

     Applications such as PhotoImpact Explorer, iPhotoExpress Explorer,
     and Paint Shop Pro (using File|Browse feature) may create extra
     files on CompactFlash or PCMCIA cards inserted into a PC Card
     reader. PhotoImpact Explorer and iPhotoExpress Explorer create
     files with names such as IMAGE*.PE* and Paint Shop Pro creates files
     with names such as PSPBRWSE.JBF. These files are neither recognized
     nor removed by the Canon Digital Camera TWAIN driver or the Canon digital
     cameras,
     but they will occupy space that would be otherwise available for
     camera images.
     Fix/workaround: erase the files to release the space on the
     the memory cards before re-inserting them into the camera. In Paint
     Shop Pro, access the Browser tab in the File|General Preferences
     dialog to uncheck "Save browser files to disk". In iPhotoExpress
     Explorer, access the Explorer tab in the File|Preferences dialog
     to uncheck "Save Folder Reference Files".

(8)  Micrografx Picture Publisher 7.0 crashes when saving pictures

     Picture Publisher may crash after acquiring images from the camera
     when a save file dialog box is displayed.
     Fix/workaround: go to Tools menu, select Options, and check the
     "Disable Prompt on New File" check box in Undo tab. Click on Apply
     followed by OK to commit the change.

(9) "Unable to open the file" message when exiting Canon Digital Camera TWAIN

     Paint Shop Pro 4.1x displays this message after exiting from
     Canon Digital Camera TWAIN Driver without acquiring an image.
     Fix/workaround: This problem has been fixed in Paint Shop Pro 5.0.
     Contact Jasc Software Inc. (http://www.jasc.com) to upgrade your
     version.

(10) Micrografx Picture Picture 7.0 crashes when exiting application

     Picture Publisher may crash when closing the application while the
     following two conditions are met: a) Canon Digital Camera TWAIN user
     interface is still open, and b) there are one or more unsaved images open
     in edit windows.
     Fix/workaround: This problem has been fixed in Picture Publisher 8.0.
     Contact Micrografx Inc. (http://www.micrografx.com) to upgrade your
     version.

(11) Considerations for Communication between the Canon Digital Camera TWAIN
     Driver and the Canon Digital Camera

     Do not operate the camera switches, remove the CF card or battery pack, 
     or detach the interface cable while a connection is open to a Canon digital
     camera. These actions may cause a malfunction with some computer systems.  

(12) Part of the TWAIN window is not displayed normally.

     The TWAIN window may not be displayed normally when some of video cards are
     used. This can be corrected by upgrading the video driver to the latest
     version. Inquire with the relevant manufacturers regarding how to obtain the
     latest version of the video driver.

(13) Accessing Canon Digital Camera TWAIN from CorelDRAW 8 or Corel 
     PHOTO-PAINT 8 on Windows NT 4.0

     Canon Digital Camera TWAIN driver may not work properly when it is
     accessed from CorelDRAW 8 or Corel PHOTO-PAINT 8 on Windows NT 4.0.

(14) Connecting to a USB Port

     Please do not place your computer into standby mode while this camera is 
     connected to its USB port. If the computer is placed into standby mode while 
     the camera is connected to the USB port, do NOT disconnect the USB cable 
     from the camera or computer. Try to revive the computer. If the USB cable is 
     detached while the computer is in standby mode, some models of computer 
     may not return to active mode correctly. For instructions regarding the 
     standby mode, please consult the manual accompanying your computer and 
     operating software.

(15) Movies and Downloading 

     Movies cannot be downloaded from the camera using the Canon Digital Camera 
     TWAIN Driver since this program is based on TWAIN standards.  

(16) Image Properties for Bulb Exposures 

     The shutter speed data for images shot for 100 or more minutes 
     with the bulb exposures may not record correctly.
