my Sync has the same issue, i just kill it off. doesnt seem to affect stability,
stays open even after youve disconnected.
i dont think this is a major issue or problem though, I usually leave it running or like i said, give it a kill! the O/S seems to be really stable.
like he said though, if you have the one u do have, (lol.. sorry, my bad sentance there!) you wont have any problems, unless its M$s fault, but hey....they'll release SPs and fixes, which we'll get for free via Dell.
you wont be sorry you went for Dell. :) -they've got great aftersales as well.. although I hear they wont give free repairs if u crack ur screen!
