The Mozilla Browser (with its derivates like FireFox) is one of the best on the planet - and it runs on both Windows and Linux. It is well designed from a security stand point, complete (support for JAVA and Flash) and rather fast (at least compared to Internet Explorer). Furthermore it has features like tabs and popup-blocking. Microsoft, in this particular case, does not appear to follow the pace of development in browsers and Mozilla is gaining market share rapidly.

The following appears to have been fixed (Great!): The server uses XML and style sheets and checks for the browser. It just kicks off Mozilla - I think it uses some IE DHTML to find frames. Ugly and should be fixed. Your only option is to use IE with CrossOver under Linux.
