I've been having trouble with XoloX over the past few days and I believe it all comes down to an incompatibility with ZoneAlarm.
Each time I ran XoloX with ZoneAlarm on first, the resources woulw plummet and the only way out was to [Ctrl]+[Alt]+[Del] my backside out of there. If you run XoloX withOUT ZoneAlarm, there should be no problem. But then there's a high likelyhood you'll get hacked, which there is right now to me. Oh dear. I'm off to see if the same works with other firewalls, brb.

Just because you don't use a firewall doesn't mean you'll be hacked. And the likelyhood of being hacked w/o a firewall is not high as you put it, especially if a dynamic IP.
More important then a firewall is a good anti-virus.

( im not saying don't use a firewall )
