Yes. I have ZA running in advanced mode, so that I get to decide what to 
do at each stage, and I gave XWin and everything else complete permissions.

Might try installing ZA again tonight and see if I can nail down the 
problem a bit more, luckily i'm behind a hardware firewall, so the loss 
of a desktop one isn't too serious in the short term, and the windows 
firewall kicked in anyway, no problems with that one. A quick google 
turned up a number of articles that said something about ZA causing 
problems with the way Xwin uses sockets, but i'm not sure yet that 
applies to what i;m seeing.
