If it's in red it denotes a warning or error message from the URLs server. The 'Result' column is the HTML result code. The only one I see for the UT main page (www.levelextreme.com) is a 404 error when looking for a file named '.wav' (That looks like a coding problem on Michel's part to me since thats not a valid path or filename) BTW, if you look at the 'TextView' section on the bottom rigfht of Fiddler you will see the full HTML returned by the server.
FWIW I don't see how the choice of browser would make any difference in this instance - Neil should see the same error in IE......
