Fresh WB6 install (registered), upgraded to WB7 beta, on WinXP (fully updated, latest drivers): WB works fine UNLESS a skinned window is in front of a window with 3D content. Then the window frame flickers. That's unfortunate insofar as I work primarily with 3D tools and of course 3D games.

The problem goes away when disabling per pixel window borders, thus it's fixable. However... is there something I am missing to get it all to work even with per pixel borders?

WindowBlinds version : WindowBlinds 7.0 (build 79 x86)
