Came across this problem today. MS Word 2002, WinXP SP2. Open an existing file. Try to close or edit it and it freezes and the filename on the taskbar flashes orange. The only way out of this appears to be to right click on the taskbar entry and choose 'close'. Asked if I want to save changes - answer 'Cancel' - all is then well. Anybody any odeas on what is happening here?
