You guys are right, porting it would require rebuilding from the ground up. I agree with you about IE, jodybingo, I've been burned too many times with it and I rarely use it anymore - basically only when another browser won't work. I use Firefox and Chrome. However, IE has definitely gotten better, and really for everything from rendering, to speed, to compatibility, as well as security. As far as security and the Tournament Director goes, however, there's no reason not to trust the TD even though it uses IE. Only local code can be run in the mode the TD runs in (that means only Tournament Director code), and the worst the TD can do is launch IE in another window, and it will only do that when requested, and only pointing to known, safe locations (sites on the Links tab, for example).
