I just entered the World of Goo Corporation for the first time, and now I can't get out of it. I am not able to move my mouse cursor below the bottom 10% of the screen, right where the exit button is! I was able to exit fullscreen mode with alt-enter, but am still unable to click on the exit button. When I bring my cursor toward the window from the bottom, it jumps right from the bottom of the window to above the exit button. I had to close the application entirely and restart it to get back to the game. Running WoG on Ubuntu 12.04.
