List problems
 

I have a spreadsheet with a list. Every time I enter anything into a cell
and hit "enter" , the sheet goes blank for a several seconds and the only
thing I see on the screen is whatever I just entered into the cell. This
happens every time I hit enter after entering something into the cell. I
have tried turning the autocalculate off, but that did not work. What could
be the problem?
