No other browsers were open, just the reply box which I was active in from time to time within the the 60 mins, never just idle, I tend to type a little, have a child interuption, then go back and type a little more.
Hope that helps somewhat.

Okay - I'll see if I can find any other explanation, but without being able to replicate I am not sure if I will have answers for you. We'll see though!
I was completely inactive for well over an hour. I got up and left my office. So the only activity would have been if the LLS server was sending info to me.
