Hello,
            I had encountered this problem earlier too. The program
suddenly crashes in mouseMove, mouseDrag,mousePress or mouseRelease
events with a message similar to the message given below. 
 
Current Java thread:
      at vtk.vtkGenericRenderWindowInteractor.MouseMoveEvent_2(Native
Method)
      at
vtk.vtkGenericRenderWindowInteractor.MouseMoveEvent(vtkGenericRenderWind
owInteractor.java:19)
      at vtk.vtkCanvas.mouseDragged(vtkCanvas.java:209)
      at java.awt.Component.processMouseMotionEvent(Component.java:5182)
      at java.awt.Component.processEvent(Component.java:4935)
 
I am not sure what exactly could be the problem. I am using vtk 4.2.2 on
Windows2k with jdk 1.4.1_02. Attached is a sample code. When I run this
code, it often crashes in my machine when I rotate the model
vigorously(in combination with resizing the window). My gut feeling is
it could be because of the presence of vtkImplicitPlaneWidget. Is there
anyway I can avoid this?
 
Thanks
Shyam
