Ephox 8.1 Applet not working in IE but fine in Firefox

Hi folks - Was wondering if anyone had seen a weird issue with the ePhox applet not being loaded in IE/Chrome but being fine in Firefox.

It just started to happen today, which coincides with a message from Java to install 1.7.0 u45 JRE, I backed out of installing this, but could there be any way this would have affected the secuirty settings of the Applet. I’m saying that, as in the Java Trace console I can see network: Created version ID 1.7.0.40 and then network: Created version ID 1.7.0.45, so am wondering whether there is something in the JRE that stops it from working in IE / Chrome when an update is available?

Any help is much appreciated.

Thanks,

Bal
