As the load library in Sys class is in a static part, my solution with the boolean is not good, except if we initialize the loadingEnabled to false.
But I don't think it is suitable for non applet application ...
So, I commented the static part for my use only, I repackaged the lwjgl jar (with error for some class, don't find the com.sun.mirror or the net.java.games.input.ControllerEnvironment libs ...).
And with this pseudo lwjgl.jar, I manage to run the gears demo in an applet. It is so fast that the gears don't run correctly (I have to open several explorers to "slow" the drawing :lol: ).
I have tested with Firefox and IE, no changes, I'm always around 120 fps.
I'm working on a laptop DELL Inspiron 8600 with 1Gb and Geforce FX 5650 128mb.
