Vista beta 2 cleaning up my computer?

Microsoft released beta 2 of Windows Vista to the public. Curious as I am, I decided to see if I could download the 3.12 GB DVD image. I got a decent 200-180 Kb/s (hey, the whole world is downloading the file), but look at the progress I am making:

Negative 22 percent? The number actually went down when the download progressed (ie: it started at -1%). Internet Explorer must be cleaning up my computer before I can download Vista. Or someone's using a 'signed long' for the filesize and download that should be unsigned... A signed long can represents a maximum number of 2 'giga' (2*1024*1024*1024). Values above that are represented as negative. Ofcourse, the really interesting question is, what happens in IE if you try to download a file larger than 4 GB?

Had I given the download long enough, the progress would have magically gotten back to positive when I crossed the 2 Gb line (both the total size and downloaded size would probably be negative). However, I decided I needed to get back to work and I'ld need my bandwidth. I'll try again tonight. IE isn't the right tool to be downloading 3.12 Gb with anyway...
