Problems w/ Java applet (alGenBuffers)

Hi all,

I’m rather new to JOAL and I am stuck with exceptions caused by my java applet.
The applet is running at http://christinadicke.com/demo/test.html

On all machines which have JOAL libraries installed, the applet runs without problems. But on all other machines I am getting:

7/8/09 3:12:05 PM [0x0-0x24e24e].com.apple.Safari[12538] net.java.games.joal.ALException: Method “alGenBuffers” not available

Any suggestion/help is highly appreciated!
