odd video problem

[songpony]

Yes, I did (prior to installation). The only ones that threw me a bit were:

9. In the “Visual Effects” tab, left click Adjust for best performance
10. Scroll the very last item on the List, and put a check beside Use visual styles on windows and buttons

If I did item #10, it "undid" item #9; I could either select "Adjust for best performance", or it would select the next radio button down if I clicked anything in the list (such as "use visual styles on windows and buttons"). One other "issue" was that I couldn't find any "enable transparency" checkbox in order to uncheck it (for aero themes). According to the list, my OS is one of those that should have this setting, but I never saw it anywhere. Other than these 2 things, all instructions were followed to the letter. If you know how to "correct" either of these 2 issues, I would be happy to do so. Thanks.
