[ODE] ODE freezes, can you help?

You will want to enable multi-monitor debugging.

Make sure to install the debug DirectX 8.1 runtime then open the DX
Properties application in the Control Panel.  Go to the DirectDraw pane,
click on the Advanced Settings button and toggle the last check box
which is called "Enable Multi-Monitor debugging".

Now the Window will not loose Focus when you are debugging.

Hi.
I have multi monitor support for my notebook. The only problem is that
device gets lost when I focus visual studio. This is also problem for
other
directx apps, including samples which come with sdk. How to solve it?

But, I dont understand what could I have written that freezes ode. Where
is
the problem? Have I initialized something wrong? What, what? Sometimes
it
works, sometimes it doesnt! I am almost sure there arent any memory
leaks,
since I checked application with fluidstudio memory checker.
But, I game I am doing this:

I initialize : world,space, joint group
I add bodies and geoms, masses to them, I put them in position
for each frame:
    I apply forces and torques to them and they move around
    When collision occures, everything gets f... up.(sometimes) why oh
why
