   [9/C++] Lost due to display uniqueness change
  Hey folks. Windows 7, DX9 Feburary 2010.When I switch from fullscreen to windowed mode, I babysit the device and everything else like I should. Reset() shows green. Once finished, mouse input goes right through the window (I can click & drag things below it.) and the device is found to be lost on the next TestCooperativeLevel() with:Quote:Direct3D9: (ERROR) :Lost due to display uniqueness changeHowever, the window does receive keyboard input. I can switch back to fullscreen mode on ALT-ENTER, and everything is fine again.Summary: I can start in windowed mode without a hitch and fullscreen mode always works. However, switching BACK to windowed mode sends everything to Hell.What gives?
