Next try:
http://madshi.net/madVRmc21b.rarIf you still have problems with 3D not activating or switching on/off when the OSD is shown, then please create a debug log for me (with the new debug build), by using the following approach:
1) Enable Ctrl+J OSD and keep it on all the time for this test.
2) Start playback in windowed mode. Let it run for 10 seconds. Do you get 3D?
3) Switch to fullscreen (are you using exclusive?) and let it run for 10 seconds. Do you get 3D?
4) Show the MC OSD and let playback run for 10 seconds. Do you get 3D?
5) While the MC OSD is visible, does madVR detect a different refresh rate?
6) Hide the MC OSD and let playback run for 10 seconds. Do you get 3D?
7) Close MC21 completely, zip and upload the debug log.
Please also tell me your madVR settings, especially those in the "stereo 3d" and "general settings" pages. Thanks!
