[ODE] Incorrect depth on trimesh collisions

[Joost van Dongen]

Hello Jon,
 
Thanks for the quick reply! I am not setting the previous transform, so that is something I will try now. However, I previously already tried moving to ODE 0.8 and I got linker errors when doing that. Compilation goes okay, but the linker gives me a number of errors that I do not know how to solve. I am using Visual Studio 7.1 and simply downloaded the win32 distributable from the ODE-site. Linking goes okay in 0.5 and 0.6, but this is what 0.8 gives me:

What am I going wrong here?
 
Thanks in advance,
Joost "Oogst" van Dongen
