Our Office 2003 and Office 2007 have been experiencing some issues recently. Most of the time it is caused by our email signature that contains 2 jpg images.
When they reply to a certain emails the images on the signatures start flashing and the Outlook freezes, it seems to be caused by word.exe. When I kill that process, Outlook starts working normally (but it closes the reply window). Now if I remove the signature from the reply or just create a new email it does not flash/blink and the email goes through without any problems.
Does anyone have a clue to what could cause this? It does not happen to all emails, but it's frequent enough to become annoying.
