Hmmm ... let me know if you find WebStart helpful

That is very interesting.

Well, I didn't have much luck with the 1.3 graphics either :-)
But, Jmol is now really only using graphics call ... I am now building the
entire image and blitting it to the screen with one call to drawImage.

I'll check it out.

Thanks for the link.
And yes, I *have* had a lot of trouble finding info on Apple's web site.

I'll plan to take you up on that :-)
