I am having the same problem on one of our PC's. I have had the problem before and found a setting on one of the MS option list that changed the ICON inversion. The problem is I don't recall which option list it was in. I do recall is was a long list of options similar to the drop down list in the view> folders options. I realize this isn't much help, but I have read a number of comments relative video cards. In my case it was a simple setting.
