I have this same problem. F8 does nothing for me. There is no EXT or ADD at
the bottom of the spreadsheet. It only happens on my laptop and not on my
desktop.

It's killin' me. Everytime it happens, I lose any data I've keyed and not
saved.

This is a new one for me. Afer opening up Excel '98 and go to a cell, every
cell is highlighted when I move the mouse. I can not put any information in
any cell. The only way to quit Excel is control, alt, delete and then it
gives me "can not quit excel". It does though after a while. Wherever I
move the mouse, the cells are highlighted. What gives?

Thanks
