Hi everyone,
 
I'm currently writing a very thin C# wrapper for ODE. Basically it just
does a lot of DLL imports and some marshalling for returning float
arrays. However I've got one big problem: After calling the
dSpaceCollide function I get a NULL reference exception as soon as I
step out of the dNearCallback function. Does anybody have a clue what
could cause a NULL reference exception just after the callback function
finished ?
 
Thanks,
  Dennis
