after each time i save, i'm having a little problem. it saves ok, then i select continue on the menu, and it begins to play the little prelevel video clip (theres 1 before each major level). if i let it play through, it works fine, but if i press any key to skip it, it stops playing hte video and shows a black screen, with hte previous levels music playing, and then just does nothing. so far this has happened 3 times, on the first 3 levels, but doesnt happen if i try to skip the video after loading the save.
