Both my browsers (Chrome v 24 and Firefox ESR with IcedTea-Web updated in CentOS-6.3-x86_64) stop working when I click View Job. After I restart, I can build a molecule, and submit job, but I cannot look at them when they're done. Chrome claims it is running out of memory, but I have 4 GB and System Monitor shows only 20% used. Any suggestions? This is WebMO 12.1 - upgrade to WebMO 13?

Is this with ALL jobs, or just a particular job?

I presume this is a new phenomenon. Have you made any recent OS or Java updates?

Does the demo server work?

ALL jobs, WebMO 12 or 13.
I have installed:
icedtea-web-1.2.2-3.el6 (x86_64) and
java-1.7.0-openjdk-1: (x86_64).
These are suggested when I run "yum install icedtea-web" on my CentOS 6.3 system.
Do you have a RedHat system with this icedtea-web version?

Please use the official oracle java distribution. This is the true and supported java.

OK, that works! However, it's not obvious how to do this so I will briefly describe what I did to install Java and 64-bit MarvinSketch. (This will be of interest to chemists who may wish to set up their own 64-bit Linux systems and have them run various open-source applications like WebMO client, MarvinSketch and others.) Anyway, I am running CentOS-6.3-x86_64 in a VMware virtual machine (4 processors, 4 GB memory, 20 GB of HD space).
Go to http://www.oracle.com/technetwork/java/javase/downloads/index.html, and under Java Platform, Standard Edition, you can read the installation instructions and download jre-7u17-linux-x64.rpm . For CentOS, RedHat SUSE as su, then do
# rpm -ivh jre-7u17-linux-x64.rpm
Java will be installed in /usr/java directory.
By default, CentOS installs Firefox ESR 10.0.5 in the /usr/lib64/firefox folder, and the plugins in /usr/lib64/mozilla. According to the mozilla website, for the java plugin to work in firefox, you need to place a symbolic link to java in the mozilla plugins folder, like this:
# ln -s /usr/java/jre1.7.0_17/lib/amd64/libnpjp2.so /usr/lib64/mozilla/plugins/libnpjp2.so
(This follows the linux syntax of "ln -s [source] [target]". Use the full pathnames.)
Downloading and installing the linux-64-bit version of marvinbeans (marvinbeans-5.11.5-linux.sh) from www.chemaxon.com per the instructions does not break WebMO client operation. Do not install the marvinbeans version that includes java - java is already installed.

Thanks! I should have pointed out that similar instructions are also in the support pages.
