hi, I just got a new iMAC and am frustrated with X11. It is installed (off of the CD originally...I have also installed it from an online dmg) and I can see the app under Applications/Utilities but when I click on it nothing happens! Similarly "open -a X11" doesn't work either. Any ideas? I can keep reinstalling until the cows come home but nothing changes. There is not a lock file in my /tmp directory. Thanks!
