I am having an issue with the alpha transparency in WB 5.01.006. I have tried the latest BETA versions and the issue remains so I switched back to the official release.
As you can see the title bars and borders are showing through. I mainly have run into this with Photoshop CS2 but after a while it also occurs with my start bar.
