GENERAL ISSUES FOR Windows Me
-----------------------------
1. GENERAL ISSUES 
=================

(1) Persistent Camera Icon Error

    The camera icon may persist, causing an error the next time the camera is
    connected, if, during a connection, the camera's power is shut off,
    the USB cable is detached or the camera automatically powers down
    after being left alone for an extended period.
    If this happens, shut down and restart the computer before attempting
    to reconnect. 

(2) "TWAIN Data Source not found. Please reinstall scanner software."
    Error Message

    If you have set the WIA Driver settings to start a specific program
    when the camera is connected, that program may display an error message
    similar to that above. If this happens, select [WIA-(your camera model)]
    as the TWAIN device in that program and use the WIA TWAIN Driver. 

(3) Camera Window Doesn't Open Automatically at ZoomBrowser EX Startup

    If you have set the WIA Driver settings to start ZoomBrowser EX when
    the camera is connected, the ZoomBrowser EX camera window may not open
    automatically at startup. To use the camera window, double-click the
    Canon camera icon in the ZoomBrowser EX window. 

(4) Error in Using WIA TWAIN Driver with 'Detail' view setting

    Using the WIA TWAIN Driver with the view setting set to Detail may result

    Thumbnails view setting to use the WIA TWAIN Driver.

(5) Camera Search Error

    If you copy image data by dragging and dropping it into another folder
    from the window summoned by clicking Explore Camera (Advanced) in the

    the Scanners and Cameras Wizard. To prevent this error, do not copy 
    image data from the window summoned by clicking Explore Camera (Advanced) 
    in the Scanners and Cameras Wizard.
