Dear Josh:

Yes, I confirm that in the above page, as soon as you turn sync on, 
and rotate one molecule wit the mouse, the left molecule jumps to a 
new center which pushes it out of view. If you zoom down to about 
20%, you can see both molecules, one rotating around an inappropriate center.

I see this bug in your page in both Firefox/Windows and Safari/OS 
10.5. However, you are using Jmol 11.3.66. It may be worth trying 11.4.RC1.

I have also seen this bug with macromolecules, but intermittantly, on 
this sync'd multi-jmol page I am developing:
http://www.bioinformatics.org/jmol-tutorials/jtat/jtatdemo/ch_comp/chapter.htm
Most of the time, the centers are correct. Sometimes, in View 5, 
where two different molecules are compared, the bottom one jumps to a 
different center. So far, I have not discerned whether the problem is 
worse with a particular browser, or completely random.

If you get the problem 100% of the time on your page, then it is a 
good page for Bob to use in debugging this problem! (When he gets 
back from Jamaica and catches his breath ...)
