I'm curious, does anyone here use IE to play the game?
If so, have you ever tried playing it in Firefox 3.5? I jump to IE to verify things are working correctly and I'm always shocked by how much slower it is. The JavaScript engine in Firefox 3.5 (and 3, to a lesser extent) is so fantastically fast.
Google Chrome is also ridiculously fast, though I can't stand the way it looks.
