Closing/Crashing GDE after going to scenecomposer or material edit(only when in maxymize window mode

What happen when you run a jme3 test? Does It throw any exception?

jme3 test u mean testchooser or what? from there it work ok(i dont checked all examples)

The main examples, like “TestWalkingChar.java”. But if you got it then your graphic card support opengl 2.

TestWalkingChar works perfectly :wink: and i known it support opengl 2, but maybe it just collide with somethin while opening scenecomposer(i dont know how scenecomposer viewer is done)
