I am not sure what has changed. But it's now working for me on my office computer and at my home. My office is Windows XP running chrome v23.0 and home is Windows 7 running Chrome also but I don't have the version info for that.
I was thinking the same thing along the lines of Java. There have been a few Java updates since I first reported this issue so maybe that was the problem.
Either way something was changed and now the site is working!!
