fluctuating fps

[Piers Prior]

when i start krp the fps goes 16 to 80 about once a second and kepps flickming really quickly from one to the other, when i am on track it means the sound and visuals are in about half second chunks
It did it in beta9 too but if i pressed the windows button, then clicked the krp tab at the bottom it would stop it, but this dosnt work in beta10b
if i then open the task manager in the background while krp is running to see what is happening then krp crashes with a 'runtime error' with this message
" bNormalizationResult failed in ../../include\ode/odemath.h:h326 "
thanks
