What OS Version are you using ?
Could you post a picture ? To do so, change to window mode and press Print Screen to take a pic. Paste that into Paint and save it.
Then upload the picture to a third party image sharing site like imageshack and then post the link here.
Whoa. Popping into Window mode cleared it. Going back to Full Screen, it stayed fully functional. I have since quit and reopened twice, and it has remained okay. So, hopefully...
Great to hear.
Let us know how it goes and please accept a solution if your problem is solved.
