Hey Monkeys
I’ve got a big problem:
I can’t use the scene composer because everytime I use it the whole JMP chrashes.
Sometimes it works for 5 minutes (if I’m lucky) sometimes it crashes right when I open a .j3o file.
I use Ubuntu 11.10 with kernel with an NVIDIA gt 220 card (latest Drivers).
I can’t see any error on the system output because the window closes immediately and I don’t get any other error message.
I don’t think it’s a memory leak beaucause JMP displays 100MB of 980MB allocated are in use when I open the .j3o.
I hope you can help me and that me englisch is OK.
Cheers
Elias
Which version? Is this beta? You can see the error output when you start the application via command line.
I use the stable Release from the jmonkeyengine.com page with newest update
Thank you for the tip ; I started it from the command line and I get following errors:
//This one on startup
Unknown option -Dsun.java2d.noddraw=true
//and this one right when it crashes
The program 'java' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 31425 error_code 8 request_code 73 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

Maybe I've to mention too that the openGL window wasn't displayed (just the gray NB background not the black background of the openGL window) sometimes it appears somtimes not. That's very strange.
Installed it on Windows and now it seems to work.
I think there’s a problem with the X-Window-Manager together with JMP (wich also can be an jVM problem).
so I have to use Windows now 
Are you using OpenJDK or Oracle JDK? We have had issues with OpenJDK before.
