hi,
I'm a big mac user, ask my friends
I worked through the course, and looked into all the little holes etc that was possible, prior to being able to offer the course, yep, as you state, I had the same, and resorted to firefox, its just about seamless, you'll see the blips if you look for it, but its not in the module/test itself, so it doesn't interfere.
E-M.
