I have the same problem, with xolox and zone alrm, my machine
slows down. so much that i just give up and reboot. So your not alone. Resources seem to be sucked dry. All permissions are set up, wish it was that simple. Got tired of fussing with it, so i just turn zonealarm off before i start xolox. Their just not compatible on certain machines with certain software or set ups.sorry for not having the answer, at least i just didn't say it works fine for me.
