>that has happened only once, again since upgrading to 2.0, i just put it down to no message being posted, but that doesn't make sence.

Ok, I see that the HTML being received is not received totally. What is received is ok but the rest is cut. That seems to be the result of a problem in the connection. As long as the HTML is not fully received, you would end up in really weird behaviors. It is important that the HTML is fully received. Do you have any utilities that are intercepting a page to not be fully loaded if bigger than a specific size? Are you using any 3rd software at all?
