You may have more than one sheets selected simoultaneously. Righclick a
sheet tab and select "ungroup sheets" if it's there.

I upgraded from Office 2000 to Office 2003 this morning. An Excel
document I
created yesterday in a shared network location that has never been touched
by
anyone but me is now opening with [Group] status. I need to activate
Autofilter, but it is unavailable (greyed) on the Tools -- Filter menu.
I
also can't locate a definition for this setting or how to turn it off, nor
do
I have any idea why it is in this "group" mode. It is definitely not a
shared workbook.

Please help!
