Sorry to disturb you. I hear the music but I have only a black screen. To avoid this, it would be better to use an older version of LWJGL as this bug appeared in LWJGL 2.0 alpha 3 and it is not yet fixed in LWJGL 2.0.1.
You're not disturbing.^^
We're thankfull for every hint. And I think a tester had that problem already but we didn't know why...
