.OBJ meshes within a complex java CT medical application. My simple java<br>
viewer test apps work fine (since I fixed a "mouse-move before<br>
initialization complete" crash - see above). However, more often than not,<br>
the CT app crashes during VTK initialization. When it initializes<br>
successfully, it works flawlessly.<br>
I have more info about the problem:<br>
<br>
1. The problem occurs on different 3 PCs with 2 different graphics cards.<br>
All support OpenGL 4.x<br>
<br>
2. When the crash occurs, the vtkError.txt log shows:<br>

<br>
3. All accesses to the VTK occur on the AWT-EventQueue-1 thread.<br>
<br>
4. Changing the order and timing of VTK initialization relative to the<br>
display of the VTK JPanel does not appear to fix the problem.<br>
<br>
5. VTK-6.3.0 does *not* exhibit the crash, but it is slow to render when<br>
moving or zooming the mesh. My simple test apps *have no problem rendering<br>
the same mesh* when using VTK-6.3.0. This should tell me something, but I'm<br>
not sure what.<br>
