Kind of a Red October related question. I use DisplayCAL for monitor calibration and profile loading..
When I play a video file, DisplayCAL detects madVR and disables itself, however once playback has stopped, it doesn't seem to re-engage and enforce my profiles until I close the JRiver media server. I'm not sure which program is causing the problem but based on the behavior I am inclined to think Media Center either isn't unloading something properly, or perhaps not signaling properly that it has been unloaded??
DisplayCAL is obviously checking the state of something and finally re-engaging when the Media Server is killed completely so I'm just not sure who to point the finger at here.
