Two Questions, one being a crash inside newton.

First question is the crash, can't find out what is causing it, the call-stack only reveals it is inside the newton.dll file, without entering from my code (nothing else is on the call stack sans thw newton.dll call). All debugging was from a crash dump, couldn't reproduce it when the debugger was hooked in I can't seem to figure out why it is crashing, no user interaction at the time, some bodies could be bouncing around but that is it. Don't suppose there are any debug symbols or whatnot? Crash does not seem to happen in release mod, but rather just a total lock-up, not even a dump. No doubt it is part of me code though, just having trouble finding it.

Second question, how do you pass a function into fastdelegate, I'm having to use this convoluted method for passing one through another function which seems to be acting odd with inheritence.
