Evert, I made the changes but am awaiting dev-access in order to push up my changes. I can not test due to the fact that both of the existing stabilizers crash on my machine. The new one crashes too :-)
But, if the pattern used to implement the existing two stabilizers is the same for the new one then I think I have it sorted out. I'll need you to test it for me. If you want I can attach the two source files if you are anxious and don't want to wait.
