It reminds me of show, IT Crowd:
"Did you restarted it?"
YES
Do it again...
Anyways, real solution for this one is to make sure that "Universal visual styles on windows and buttons" is check marked in "Visual Effects".
1. So click Start and right click over "my computer"
2. Select "Properties"
3. Top left, click on "Advance system settings" and then "Advanced"
4. Under performance: click "settings"
5. At the bottom, check mark: "Universal visual styles on windows and buttons"
Worked!!!
