SYMPTOMS
While you are playing a DVD movie on a Microsoft Windows XP-based computer, a semi-transparent window or a semi-transparent dialog box that appears on your screen from another program may flicker. For example, the Input Method Editor (IME) toolbar may flicker if it is visible on the screen while you are playing your DVD movie. This problem also occurs if you start the program while the DVD movie is playing. If you move the DVD movie window, this flickering may become more pronounced.



CAUSE
This problem occurs because some of the DirectDraw features that your DVD movie player uses interfere with the presentation and the appearance of semi-transparent windows.



WORKAROUND
To work around this problem, close the window from the program that is experiencing this problem. In some cases, you must quit the program to close this window.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
