OK, I can reproduce this problem even at
http://chemapps.stolaf.edu/jmol/docs/examples-11/new.htm
The problem:
After a few script invocations, specifically with the Mac OS, the applet
appears to not be responding. A page resize starts it up again. In
actuality, the scripts are working fine. it's just that nothing is being
displayed. The applet is "frozen". Even quick tapping motions with the mouse
that just slightly change the orientation can generate the problem. Again,
the applet is not frozen, but something is keeping it from doing its update.
You can still enter commands using CTRL-K followed by keystrokes. For
example, [CTRL-K] javascript "alert('testing')" [ENTER] does pull up a
message box.
Thoughts: This is a serious problem. Very odd that it is just now that we
notice it. It's not like Jmol hasn't been used on a Mac.
[Jonathan Gutow -- have you noticed this before? Recently?]
It's could be a Mac OS bug or a browser bug, but more likely it's a Jmol
problem. I will start debugging from our end do see where the hang-up is.
Could be a threading issue, an operating system updating issue, or a Jmol
bug.
Basically what happens in Jmol is that when changes are made by scripts and
such, Jmol sends an "I need a window update" message to the operating
system, and the operating system is then supposed to send Jmol the same sort
of "update your window" message that happens when another application that
was obscuring the page. Something is hanging up that operation.
Question: Is this happening with Jmol 11.6 or just Jmol 11.7?
Question: All browsers on the Mac? My tests were with Firefox. I don't see
the problem (yet) with Safari.
