This is not a bug. It happens when the download is handled via a script as opposed to via a direct link to the file. I experienced it with our own site walki-talki.com (see sig). When we were testing our site with different browsers, I believe we got the same result with other browsers. Eventually, we had to resort to a less secure, direct link to the file to handle downloads because, as you guessed it, M$ Internet Explorer (truly, the lousiest browser on the planet) could not process download via script at all!

Cheers.
