PHP Minify - Internet Explorer not determining file type

[Beitarist]

I'm using PHP minify -> http://code.google.com/p/minify/ to minify my javascript files into one document and then supply it to the browser.FF, CHROME, SAFARI all render the dynamic js file correctly when the script is calledIE says that min failed and attempts to launch a file download and then is unable to recognize the file type even if I directly refer to it in the browser.
