Hi Nancy,
It's not surprising that applications from Microsoft would support only IE. If your application is Microsoft's .Net and SQL Server, you may lock yourself into Windows and IE. I'm writting a web based application and constaintly checking to insure it is cross platform on all the most used browsers like Mozilla, Netscape, Opera, Firefox, and IE. I use mostly perl and HTML with a little javascript, and the app works very well on all these browsers whether in Linux, Windows, or Unix.
All the browsers, except IE, adhere closely to web standards, so if you code to web standards you shouldn't have any problems. One way to do this would to be write your application to Firefox, and then you can be sure it will run on IE. IE has many extension, especially activeX, that are not web standard and hense not support by other browsers.
Below are a couple of article that appeared in the November 22, 2004 eWEEK Newsweekly that go into the subject in more depth and give some indication of where the issues stand at this time.
