All works fine except for the first run (Aero > Dallas Maverick):
These latest builds (WindowBlinds 6.1 (build 83 x86 - Vista Edition) + WindowBlinds 6.1 (build 84 x86 - Vista Edition)) are really problematic.
1. Open WindowBlinds config panel
2. Apply default Windows Vista theme > Aero (WindowBlinds will close automatically)
3. Open SDC and update WindowBlinds (6.02 > 6.1 or 6.1b83 > 6.1b84)
4. Reboot
5. Try to apply any skin (example Aero > Buzzz or Aero > Dallas Mavericks)
6. Doesn't work (default classic theme)
Event viewer > The Desktop Window Manager was unable to start because a composited theme is not in use + The Desktop Window Manager has exited with code (0x40010004)
Log off, log on and the problem is gone.
[Tested with 2 Vista installations, same problem]
