While working in excel workbooks, all of a sudden the cell
I was in became highlighted and anywhere I moved the
mouse, all the cells became highlighted. I used excape
w/o any luck - then I used F8 and it corrected, but it
keeps highlighting and I don't know what to do to fix.
Also, I am unable to get any of the tabs to open when I
click on them - they turn "white" but will not open. I
must have hit something to make this happen, but unsure of
what. Please help.

This is a *not* uncommon problem.
