Error using webstart demos

[AW999]

I recently got a new computer, and the webstart demos no longer run - apparently lwjgl.dll doesn't work with 64 bit systems.  The applet demos still work fine, however.
 Here's the error log for the Blue Thunder demo:

The webstart examples are rather old. The version of LWJGL that i was using back then didn't support 64bit. I should really update them...

 What about the version of LWJGL included with the development files?  My main concern is the compatibility of my own JPCT-based app once I get it done, since I might do it as a webstart app rather than an applet.

That one includes the 64bit binaries. However, it has a bug with newest ATI Catalyst drivers. You have to wait for LWJGL 2.2.3 to fix this or use the nightly build instead.
