Motorola Atrix 4G :: Auto-Screen Rotation Is Not Working

I have noticed that my screen rotation no longer works on my Atrix. The phone still detects the correct orientation (AndroSensor app's 'Orientation' degrees change correctly as I rotate the phone). Games that rely on the accelerometer still function normally. The operating system just seems to do nothing when I rotate. Browser doesn't go to landscape, and other apps that normally can switch to landscape, just don't. The setting to Auto-rotate is checked.I have pulled the battery, I have rebooted, I have tried changing settings, rebooting, changing them again, but I can't get it to work as it did a few days ago. Searching this sort of problem online seems to come up with similar issues with other people across a myriad of different Android devices, yet no one really has any solution on how to fix besides doing a 'factory reset'. A factory reset doesn't seem to be a good fix for this to me.

The closest reasonable explanation I can come up with is that with the added Motorola software, there might possibly be another 'rotation' setting behind the scenes that we can't access that got out of sync with the normal Android rotation settings (read on how this might be an explanation for the problem on Samsung phones), but who knows what is really going on. Very annoying though, since the phone sensors appear to be working properly. I can't even write a simple text message in landscape mode because of this, making it frustratingly difficult with the small on-screen keys on the regular mode.
