[gl4java-usergroup] Win 2000 GLCanvas crash on disposal

[<NM...@th...>]

Hi,

I have an application running under WIN2000 using GLCanvas. When the time
comes to exit my app I simply do the following to clean up the resources
used by the GLCanvas :

        try {
            cvsDispose();
        } catch (Exception e) {
            e.printStackTrace();
        }

After this call I do a System.exit(0)  and I am out.

My problem is that every 1/3 exits I crash before the standard System.exit
() is called. Below I have included the error log that is always produced
on this crash.  What is weird is that it only happens some of the
time(although still too often to be acceptable).  Also, I regularly run my
app under WinNT and this crash has NEVER occurred.

Am I cleaning up after a GLCanvas correctly?
Any suggestions?

Thanks a bunch in advance,
Noah Keen
