Here's the situation..
I had my wwgpe.xls file open.
I played around with it, but never saved.
I opened another Excel session via the Start menu.
Worked in that new Excel session for a while, and saved.
Went back to the wwgpe.xls file and didn't need it so I clicked the X at top right.
Received q if I wanted to save.
Responded No.

I then received the "Code execution has been interrupted" problem. This doesn't seem to be happening for all users on their machines. Is there any possible fix for this?
