I have just installed cygwin/x and have the problem of "cannot open Display 127.0.0.1:0.0.
Looking at the FAQ, it seems to be a problem with my firewall, which is McAffee Personal Firewall 4, which i use to protect my broadband Connection. Has anyone had the same problem, and is there a solution?. It must be very common now with broadband Thanks Peter Attwood
