Task bar Icons appear in low resolution

All of my task bar icons have changed to a lower resolution. The only things that haven't gone low res are the start button itself and some AOL mail, im, and search icons in the center section of the task bar. The notification area is all low res (printer, volume, yahoo mssngr, etc). Somebody please let me know how I can correct this. It doesn't seem to impact anything else that I am aware of but it just is bugging the heck out of me that I can't seem to figure out how to get things back to the way they were down there. I don't suppose there is any association, but this seems to have occurred about the same time I used Microsoft's Windows Vista Upgrade Advisor.

Thanks people!

On desktop...
Right Click -> Properties -> Settings Tab
Make sure "Color Quality" is "Highest (32 bit)."

Thanks for the help Rob. Turns out I already had it at "Highest (32 bit). It didn't fix my problem though. Anybody else have any ideas?

Thanks

I did a restore to the last point before I used windows vista upgrade advisor and everything is now back to normal, but I have no clue yet what caused it. Go figure.

Thanks for helping
