LF2 is not working properly in windows 7

[Shtrudel]

When he said "spam f8", he meant for the key that drops items. too many objects on the screen at once will cause the game to crash, no matter how strong your PC is.
It also happens when you have too much tile sets (characters, BGs, items etc) to load. even if it load properly, they will eventually crash.

I'm not sure why either happen, but the problem is similiar to Jazz Jackrabbit 2, where when you tried to load a save file of a level with more than ~1000 tile sets, the game carshed.
