Some of my users complains about problems opening Excel documents. About 2
sec. after they open a document it close automatically. I have found out that
the excel.exe process stay as an active task and can be closed from the task
manager.
It is not happening every time but almost! I have tried starting Excel in
safemode, but with same result :-(

3 out of 18 users having this problem and are all are running Windows Vista.

Any ides troubleshooting this matter?
