SYMPTOMS
When you input characters from the keyboard on your computer, characters may be lost, and characters you expect to see in the document may not appear. This problem occurs when Microsoft Word 2002 runs on Microsoft Windows 98 or Microsoft Windows Millennium Edition (Me) and an Accessibility client runs at the same time. The Accessibility client repeatedly calls the Word document window by using the AccessibleObjectFromWindow application programming interface (API) for access to the IAccessible interface.
The severity of this problem is directly proportional to the number of calls that are made per second and the thread priority of the caller at the time of the request. The more calls that are made per second and the higher the priority of the calling thread, the more key strokes that may be lost in processing.
The problem does not occur in Microsoft Word 2000. This problem also does not occur in Word 2002 if you run on Microsoft Windows NT, Microsoft Windows 2000, or Microsoft Windows XP.
