Also, for some non-CTF levels, the program automatically switches to the ending screen (when you quit the game) and quits when I reach a certain point. This point changes from game-to-game. For example, 70s Groove terminates when I reach a spring after the first caterpillar and am about to jump over the pipe organ. Under Siegeness ends as soon as I hit the bottom (after falling) and move along the bottom-right path. Some one suggested that this might be related. I was wondering if something got corrupted.
