Can't open Excel from Office 2007 due to spell check
 

I can't open a single file in Excel now without a permanent, and I mean
PERMANENT dialogue box stating that I need to either perform a spell check
(current files) or that the spell check is complete for the entire sheet
(blank worksheet/workbook). Even if it's complete I click 'ok' and the
dialogue box will not go away.

This seems like a virus but I've scanned the entire computer as well as
Excel.exe and there is nothing detected. Has anyone ever been essentially
handcuffed and locked out of the entire program & somehow been able to solve
this bug?
