When I go to the Options menu > Tracker Tab > Camera Settings and click Open, I set my settings, hit apply and ok. And they do apply to the camera in the video viewport. However, as soon as I hit OK on the Options dialog box, it takes a second or two to save, then the camera reverts back to default settings. So things like brightness, contrast, etc, all revert to default, making it useless at tracking. The only way I can get it to work now is to launch Opentrack, open options, set all of my camera settings, and leave the options window open while I play. Which is not ideal. It just started doing this too with no apparent changes before hand. It used to save the camera settings.

Any thoughts on what could be causing this?
