---- Reported by nikojn 2004-05-29 03:26:53 ----

Two JInternalFrames are added to a JDesktopPane. Both of them have GLCanvases 
controlled by Animators. Moving one of the windows on the desktop causes a non-
recoverable error, a crash with the following trace:

The environment is:

- JOGL nightly build dated 20040517
- WinXP
- ATI Radeon 9700 Pro, with 4.5 Catalyst drivers
- J2SE 1.4.2_04

Note: this issue probably somewhat overlaps with the existing issue #30.
Here is the complete source code for the test case:

---- Additional Comments From kbr 2005-01-31 09:46:08 ----

This problem is caused by bugs in ATI's OpenGL drivers. The test case works on
NVidia hardware. Bug fixes and additional workarounds have recently been checked
in to the single-threaded workaround designed for ATI hardware. The attached
test case works properly with the code in the CVS repository, which will be
introduced in JOGL 1.1 b08.
