Actually, I just found that this problem is reproducible.  My graph is 
displayed on a
TitleWindow.  If I close the TitleWindow while the graph is animating the 
layout, the
next time the TitleWindow is popped up to display the graph, the error occurs.

Hi, I just committed some sanity checks to the VisualGraph.draw() method. It is
possible that this also fixed your issue, but I cannot be sure. Could you 
provide a
very small demo application (and its code) that shows the fix, or if you can
reproduce the fix with the vgExplorer Demo application, just describe how to do 
it there.

If I minimize and maximize the window of the vgExplorer (running in standalone
flashplayer), I get no more crashed.

No further feedback, assuming it is fixed.
