I've been learning this the hard way today. :-)  Adding torques made
my simulation blow up left and right, but since converting to motors it's
been much more stable.

A couple of tangential questions...

Anyone know of a Windows utility that will make an MPEG of my app as it
runs?  This is probably just wishful thinking on my part, but it would be
nice to be able to share MPEGs with the group.  

What does LCP stand for?  All I really know is that it's the key thing
that makes ODE tick.  Is there an URL that will give me an overview of
what it's all about?

Thanks.
