SYMPTOMS
When accessing the body of a message using the Outlook object model from within the OnSubmit event of an extension dll, an orphaned window is created and left on the taskbar. This only occurs running Outlook on Microsoft Windows NT, version 4.0. The window can be maximized and appears to be a valid duplicate message, however it does not function correctly.



CAUSE
This is an operating system issue causing a problem with the way Outlook uses its internal cache.
