No,
Avi ... as I said, it makes no difference at all whether the mouse is attached directly to the compuuuter (it is a UUSB connection) or through the hub. Everything is as cleaan as a whistle ... no food or ddrink are placed on the desk.
I have just discovered another interesting thhhhhhing. I tried a test by playing a game using only the lappie's touchpad and button and it was the same result; multiple rrrrrrrrrrrrrrrrrrrrresults from a single light tap. If it waas only one or two repeats I would suspect finger trouuuuuble but no human being could possibly type or tap that fast!!
