Dear all, I've been working this last week on Jmol in SAGE math (www.sagemath.org). I thought people might be interested in what I've learned. In the process I've unearthed a number of issues on MacOS.
a) When launching a lot of applets on a page in FF sometimes not all the applets finish initializing. There appears to be a memory/process collision problem. It is so intermittent that I have not been able to pin it down. Things seem to be worst on 64 bit installations. b) Safari also has problems with launching a lot of applets. This one I could trace to memory issues. I think Safari has a memory leak as the problem occurs even after most of the applets are forced to close. Interestingly, this problem shows up as a security violation when calls attempt to get an image from the applet as a string. c) Jmol works very well in Chrome on MacOS. I was unable to produce any of the oddities I saw in FF or Safari. Notes: 1) The tests involve launching pages that have lots of Jmols on them. It is very easy to run up against the memory limits of the JVM in the browser, so the launches are carefully controlled to be sequential and no more than 4 of the applets are allowed to stay open simultaneously. A repeating javascript process replaces an already open Jmol with an image before opening the next one. 2) To see examples of what the pages in Sagemath look like go to http://141.233.197.45:8888/home/pub/0 3) FF and Chromium work very well on Ubuntu Linux 4) I haven't performed these demanding tests on a Windows machine yet.
