Thanks for finding this bug.  The problem was caused by the fact
that times in a Vis5D file are days since 1900 instead of seconds
since the epoch.  In the animation system, I was calling
doubleToIndex() using a value in units of seconds since the
epoch which would come back as an index of -1.  What you were
seeing with the jump is that the other window would jump to the
last timestep when it got this value.  I changed it so it would
use the correct units and now it seems to work.

This is a problem I still have not figured a solution to.  What
happens is that both widgets are sharing and both trying to control
the animation.  The workaround is to always control the animation
looping from one window.

Yes, the problem was all mine. ;-)  Thanks for the detailed
message and the bundle.  Very cool animation!
