Have my game running in C1 Classic now, everything looks fine exept physics.
Also I notice that there is still a bug in platform behavior:
The monsters in my game use platform behavior+custom behavior, when I set the platforms as solids everything works fine but when I set it as platform they drop trough the platform randomly when you walk away from your pc and the pc go at screensaver. It happens sometime's to when your active playing.
Also I had the monsters jumping to heigher platforms and that go wrong when you for example have a other programs running and swap between them, I notice it when I swap between the game and msn as first, the jumpstrengt looks like its half what they suppose to do, hope that in C2 a lot of issues get improved and hope in C1 it get improved as well
