They are not using Safari, there is no menu, and you cannot turn off the popup blocker. Someone has written what must be the worst piece of software ever, using an embedded mozilla browser component that takes up the whole screen.
No new windows, no menus, no copy/paste, no switching keyboard layouts, it's a disaster. Give me Windows any day.
I finally got so disgusted that I turned the machine over, unplugged the ethernet cable, and plugged it into my laptop (only about 8cm long so I had to juggle). Unfortunately, they seem to be using MAC address authentication so that didn't work either.
