Hi Kelvin,
I've tried your program and everything was OK.
So, I changed the program to reflect my case (you can find the files as
attachment).
The class DummyJFrame has two buttons:
"One Frame" - when you push the Button one MultiCanvases is
instanciated and made visible. If I close this window and push the
button again,
it works. BUT, if I leave this window open and push the button again,
JVM crashes.
"Two Frames" - when you push this button, 2 different MultiCanvases are
instanciated and made visible. Everything works OK (under the condition
that no other
MultiCanvases instance exists).
Now, can somebody explain me why this case works???
The program works just fine on a Matrox Millennium G 400.
So, it might be a driver problem after all.
I would appreciate if somebody from this list could test the program
(especially on NVidia cards!!).
Thanks,
Octavian
