I open excel...and when I go to click in any cell or row or column...the entire column or row highlights and is like a runaway train! Then when I try to shut it down it won't shut down...I have to control alt delete and end task...it then says "Microscoft excel can't quit" and then finally it quits. It's like a crazed animal. HELP! I need to work on the damm file...this happens with any excel files I open...
