We are trying to solve an odd issue that only seems to crop up on nvidia cards in certain situations. So, we need your help to gather a little data.
Please, update the latest from CVS. This will add (among MANY other updates), the ability to display normals in SimpleGame by using 'n'.
Once you are updated, run TestTerrain (any terrain test will work, but TestTerrain works best). Once the test is up and running, press 'n' to display the normals. Does it crash? If not, move around and run the test for at least a minute.
After you've done that, please report the following:
CRASHED?: Yes/No
Nvidia Card:
Nvidia Driver version:
CPU:
OS:
Non-nvidia users are welcome to try as well, if yours breaks, give us the same information.
(P.S. If you are an OpenGL wiz, and have an idea of what could cause a native crash like that, please let us know 
)
Thanks,
Mark

The nvidia driver is an old one, but the newest gives me problems when i shutdown the system (so no 3d problems). I can walk for minutes and turn on / off the normals just fine.

Those who had crashes before: ServerStyle and Sonicviz, please update from cvs and try again.
Thanks, again, everyone. I think Renanse might have taken care of it (crosses fingers)
Worked like a charm, got the red grid covering the terrain…
The results of another half-asleep programming session… probably fixing the results of a previous one. }:-@

drfugly, you get the crash from doing what Mojo describes? Or you just get a crash and posted it here for some reason?
Asking just to be sure, because since as you can see it seems to have been fixed for the others since October 2005.
drfugly, as you currently play around with swing thread and such - maybe you have called some jME methods from that thread, while rendering is done in another thread? This can cause such problems, as lwjgl (GL) does not allow being called from multiple threads. (as Llama asked, this seems unrelated to this topic)
actually i came to this thread from a link that mojo posted in another thread, i didn't notice the dates and did the test
Now as it turns out, I do crash from doing what Mojo describes.
Weird huh?
In that case, what version of jME are you running, and can you post the complete trace? (like sonicviz')
Hi!
Tried with the latest cvs code. All worked fine.

- When i run TestTerrain, it doesnt crash, even after two or three minutes with normals on. However, I get common errors when I try to run my own program with terrain, which differ depending on what code changes ive made.
hope this helps, please find a solution quick!
if you need me to give you the errors, just ask. thanks
