I'm trying to make a kind of black glass theme, kind of like the Vista taskbar was, but for Win 7. So I want to replace the default look of the windows for something I create, so for starters I exported the top frame and did this graphic in Photoshop:
Since the top corners are rounded I saved the graphic as png with transparency, which was the original format WSB exported. In fact, I basically worked on the exported file so it would have the same dimensions and DPI.
When I import the file into WSB it respects the transparency just fine. However, when I click on test, the transparency is not right. It changes depending on the background, but here's what I mean:
So how can I get around this problem?
