The transparent wow image you see over the forum you see is the actual game running. The jpg doesn't do justice to the quality, everything looks good and clear on my computer.

I used nview desktop manager before to do this kind of stuff but since its broken on vista I had to look for an alternative. I found xneat and its actually much much better, its usable on windows using directx, has extra features, is less demanding on the system and doesn't randomly bug, causing small annoyances and being unusable until a computer reboot. I can use the internet with wow still viewable and transition from one to the other smoothly.
