By the way, when you're using WindowBlinds, turn it off for SRB2 when you're playing in OpenGL mode. Otherwise the window will not be positioned correctly, because OpenGL likes to be dumb and discard the skin you're using.
To turn off WindowBlinds skinning for SRB2:
- Double-click the WindowBlinds tray icon.
- Go to the Per Application section.
- Click Add Per Application setting. In the following dialog, choose SRB2win.exe.
- In the next dialog, check the box that says "Ignore this application and do not skin it." Click OK.
After doing the above steps, you should be all set.
