Now here is the funny thing. On that page I had no issues other than a little stutter in some places with XP useing Firefox 21. However IE8 Had a major issue and gave the error beeps as mentioned above. Once you do get to the main page data thgh all seems well as this log fragment from I E shoows, though it is encountering some strange things.

IE8 and XP on the page mentioned.
