I have expressed frustration due to issues such as this. I even stayed away from PC for a couple of weeks until my blood pressure returned to normal. (I was lucky if I got 30 seconds - it was mostly 2 minutes plus!)

My computer is squeaky clean and to this day, I maintain the problem was not on my side.

It has gotten better though (since DocJohn changed servers or something a month or 3 back) - and when it does happen now - I just leave PC for a while.

I agree that it is seriously irritating though.
