auto filter blue arrow in wrong column

[davegugg]

Hi

I have a coworker whose excel seems to be bugging out. When she sets a column to filter with the autofilter, the column arrow stays black instead of turning blue like it is supposed to, but the arrow on a column 7 to the left of the filtered column does turn blue. This column has not been filtered. Has anyone heard of this problem? What could be causing it? She only has SP1 installed, so I thought maybe that is the problem. She is currently in the process of updating so we will see if that corrects the problem.

Thanks
