Thanks again. Another clue is that when I go to: Tools/Options/Mail Format there are 3 buttons at the bottom of window (stationery, signatures, and editor options). None of them have any effect. This suggests that a number of pieces are broken!

My computer has a bit of a different startup. It books directly to a non-admin Visitor account from which I log off and log into my Admin account. The Visitor account uses Parental Controls to limit program access. Typically when I install programs that are set to install for all users I have to play a few games to convert it to the Admin only account. I'm wondering if this is somehow killing certain parts of Outlook?
