Within the last week I've been unable to tab through the boxes of my "program" using the up/down, left/right arrows as I have in the past and when I opened up excel tonight, the cursor is an open square box rather than an arrow. when I put this square box over a cell I have to left click several times before that box is hi-lighted for use and if I right click the box, I get the white fist like it is grabbing the cell and really it does nothing. What did I do to cause these issues and how are they corrected? Any help would be appreciated and thanks in advance.
