Java Web Start lwjgl app hangs at first execution but thereafter runs forever

Hello,



I am close to finish my first JME Project http://www.elaspix.de/Weihnachten/HaengYourFriends/Elaspix.jnlp.

I want to deploy it via Java Web Start using lwjgl-extension.php for native libraries.



The problem is that the application hangs only at the very first execution on a newly installed system. After this, for the 2nd to x-th execution everything works perfectly. Even a complete deinstall of java, JWS-Application, or the lwjgl ressource-files can not force the system to hang again.



Does it sound familiar to you? Do you have an idea what the problem is about?



Should I use my own lwjgl sources instead of using the http://lwjgl.org/jnlp/extension.php ?



Thanks a lot for your time!
