I just tried downloading the file via a text-mode browser on a Linux machine, and after getting the "server too busy" error a few times, it paused for a few seconds then exited with this error:"500 unexpected EOF before status line seen"This means that your server just closed the connection before sending any response to my machine. (No error, no file, no nothing.)This may be what is causing some people (myself included) using Internet Explorer to get an endlessly spinning IE logo with a partially-filled progress bar. I believe it would spin forever in this case. This may indicate a bug in your IIS web server, but I'm not sure. Just thought I would pass it along.

Update on this ... I wrote a little perl script that goes into an endless loop attemting to download the file, sleeping 5 seconds in between attempts so as not to hammer on the server. If it fails, it displays the error, and if it succeeds, it saves the file then exits.After numerous "server too busy" errors, and the occasional "500 unexpected EOF" error as described above, it finally got the file.So, my advice to those of you getting the endlessly spinning IE logo is to cancel and retry. I let one of my IE windows spin for over 2 hours before IE finally gave up and claimed a DNS error. (That's Microsoft's default error that it shows when it doesn't really know what the problem is.)
