I have a new strange bug in greenfoot.. I am using the stand alone version on my usb and today I tried to open it, but the screen went black, told me that the nvidia driver crashed, greenfoot closes itself and the nvidia driver crashed again... That happens everytime now.. I got it to start by starting five instances at nearly the same time.. somehow one survived the crashing marathon after that but it is going on my nerves to restart nearly everything I have opened before, because of this...
