Excel Problem: Cursur disappears over Sheet

D

Don

I have rescently had a spreadsheet sent to me with a price
list with macros which ran very well. Since that time my
cursor disappears when it is over a sheet but reappears
when the mouse is moved to the top menu or the side bar.
It must be a macro problem. (?? Virus). I have run an
updated Nortons Antivirus check with no viruses found.
This must be an Excel macro error. Can anyone help me to
correct this problem?
