How come my video games stopped playing at the same resolution when I rotated my screen?

Q: I was rotating my screen on my ThinkPad and I must have pressed something (?) because a game that I had been playing for several months all of a sudden shrank and a black border appeared around it. Also my pen for my tablet would not longer work. I have changed everything I can find a suggestion for and nothing fixes it. I finished that game, uninstalled it and installed the next game in the series (Pogo Game). The new game has the same problem but NO other program was affected. Help!
