Ken:
Do you mean when your moving a gear...or simulating?
Can you describe what your doing.. the gears really should
never get out of sync, if they do its a bug. Id like to know how
to reproduce it if I can.
If its complex to explain because its a project, post it here and describe how I
can see the effect of which you speak. Ill fix is up if I can..
Thx
