Hello,

I am a new user to Excel -- I apologize in advance if I don't have the
correct vocabulary for my problem.

I am using Excel 2007. I have accidentally "locked" my Excel file (I was
trying to execute a command in another program and clicked on my open
spreadsheet by mistake). Although I can see all of the content and navigate
between both sheets, I cannot select any of the cells. My hunch is that this
has something to do with the Protect function, but the sheet and workbook do
not appear to be protected. I cannot simply Undo this mistake as I closed
the file, thinking this would solve the problem, but the locking appears to
have been saved.

Please help if you can! Thank you.
