[vtkusers] vtkPanel: IllegalMonitorStateException

[Jeff Lee]

All updates to the renderWindow should (must?) occur on the AWT event 
dispatching thread.  Use SwingUtilities.invokeLater() method from your 
createGui method (create a Runnable task and schedule it to happen on 
the Event Dispatch thread).  Are you spawning threads to do this?  Do 
you have a sample piece of code which demonstrates the problem?
