Suddenly, a sheet I've been working on will select two cells, the one I
select and the one to the right of it, whenever I click on it. This problem
had popped up once before, and I just closed and reopened the sheet. Now,
I've gone so far as to restart the computer, and it won't clear. It only
happens on the one particular workbook, all others are fine.

Has anyone else had this problem, or know of a solution. I'm on a Sony Vaio,
running Vista Home and Office 2007 Standard Excel.

Thanks in advance.
