[X4U] Not sure if I should ask this here but I have a excel question

[Robert Ashton]

I have one spread sheet that my cursor doesn't change. It stays as an  
arrow. All the rest of my spread sheets the cursor changes as you  
move it over different cells. To edit a cell or to add to a cell I  
have to double click in it. I can't even save the spread sheet as  
save is grayed out. All other spread sheets are fine. Any ideas would  
be appreciated.  Bob
