I haven't had any trouble with ComCast out here... hmm. Wonder if it's just regional differences, or what. Maybe they hate you.
I don't think it's exclusively Comcast. But I have a lot of trouble with pop-ups and there's a virus or something of somekind I can't get rid of.
What happened this time is that uninstalling Firefox made it impossible for me to open Comcast without telling it to go to IE every time, even when I check the box for "always use this program."
