I recently noticed that a colleague, using a Mac with Snow Leopard OS 
10.6, has Java 1.6.0_24. In contrast, the java running Jmol on my Mac 
with (plain old) Leopard OS 10.5 is version 1.5.0_28, despite my 
having run all Apple Updates.

If you are using (plain old) Leopard OS 10.5, please check your java 
version and let me know what it is (click on Jmol to open the menu, 
then About, then System). I am wondering if I have somehow messed up 
my java installation, which might be related to problems I'm having 
with copying and pasting in the Jmol Console.

I once tried to install 64 bit java. Now in my In my Java Preferences 
app, under General, I have "run applets within the browser process" 
and the applet preference sequence is

(checked) J2SE 5.0 Apple 32-bit 1.5.0_28-b04
(checked) Java SE 6 Apple 64-bit 1.6.0_25-b07-334
(checked) J2SE 5.0 Apple 64-bit 1.5.0_28.b04
(unchecked) JSE 1.4.2 Apple 32-bit 1.4.2_22

With the above sequence, Safari, Firefox 4.0, and Chrome all work 
with Jmol and use java 1.5.

When I uncheck the 1.5.0's, leaving 1.5.0 32-bit at the top of the 
list, having only 1.6 checked as second in the list, Safari says I 
have java disabled (it is enabled in Safari preferences), Firefox 
crashes reproducibly, and Chrome says java is disabled.

So then I move the one checked item, 1.6, to the top of the list. 
Same behavior.

So keeping 1.6 at the top of the list, I check 1.6, and both 1.5's 
(you can't check just one). Now Jmol works again in Safari, but 
reports using 1.5.0_28. In Firefox 4.0, the menu doesn't respond to 
clicking so I can't see the report. Chrome uses 1.6.0_24 but Jmol 
stays blank white.

Does anyone have a suggestion? 
http://developer.apple.com/java/faq/#remove says the only way to 
clean out java is to reinstall OS X! My big mistake was to try 
installing several versions. This seems one of the few areas where 
Windows behaves better than OS X.

Thanks, -Eric
