Excel closes when Outlook restored
 

I've got a user with Office 2002 (not my fault, I swear!) and her problem is
this...

She has Outlook 2002 open, then minimizes it. She opens an Excel 2002
spreadsheet and does some work...(of course she doesn't save it....sigh) then
she minimizes Excel and restores the Outlook instance, which promptly CLOSES
her Excel instance. I know I've heard of this, but I can't remember where.
Any suggestions, other than her closing Outlook when not using it, and the
lovely SAVE EVERYTHING every minute.
