 Hi, if I have grasped your problem right then I think
you are using the application template that is sent in
ODE package.
/* I am taking in windows  */
 The drawstuff(windows.cpp) is the parent which
actually calls the ODE fucntions through dsFunctions
struct. windows.cpp has a thread that calls simulation
step and graphics step once every loop.

 To come out of this problem I have ported Drawstuff
to MFC compatible class which used CStatic frame to
render. Call dSpaceCollide in a separate thread,
possibly in a windows Timer or multimediatimer or a
thread at higher rate.  Now graphics rendering could
be limited to 30 fps. in a different loop.

 I could send my MFC implementation of ds if required.
