Screen Problem
 

I have been working on a worksheet and programming it to do what I want it to
do. A few times something has happened and the autorecovery window has poped
up having me booting me back to the last auto recovery. Now a section of the
spreedsheet is blanked out on the left side of the screen from the top of the
spreadsheet and down about 30 rows and over about 3 inches. I can't get it
to go away. Any ideas what I can do?
Thanks
