The cursor change from a pointer to a square black block in Excel. There is
also a square black block on the far left of the top menu bar. It makes it
difficult to select a cell and it blacks it out as I pass over it.

I have run McAfee and spyware checks, detecting nothing. This unwanted
cursor style comes up in every file.
Any suggestions?

Mark- ever get this resolved- I have same issue? Also, in all of
Office 2003 I can no longer sort documents by details, only icons. The
Details button is there and active, but does nothing.

Thanks.
