I knew I had to do something special with my PAX Prime DOTT special edition posters, so I got them framed and hung them in my kitchen! Thought some other people might like to see what I did I had purple tentacle matted with green and green tentacle matted with purple, I think it turned out pretty well.
I believe I have the same problem. It seems to only affect me in fullscreen mode, and the mouse cursor seems to get sort of locked to the upper left part of the screen. If I maximize the window in windowed mode I don't have the problem.
