I used mozilla browser to download a video chip from URL:
http://oxygen.lcs.mit.edu/videos/collaboration.mpeg. First it started
downloading normally, at speed 3k/s ~ 5k/s. From list view of download manager
dialog, that file sized 81008 KB, a big file for me. The transfer speed between
mit website and my pc is slowly. So I waited patiently. 
Later I download another file from URL: 
http://www.alice.org/downloads/authoringtool/2004_09_15_pm/Alice.zip. Download
manager told me that file size is 63488KB, the initial transfer speed was about
1M bps, but the speed droped a little by little. Alice.zip downloaded size
reached to about 5M bits and the speed kept on about 300k bps. So you can see
,there were two simultaneous download activities at that time, one quick ,the
other slow. 
But an error happened, Alice.zip download activities seemed stopped,for the
downloaded size didn't increase and speed froze at 300kbps, never change. So did
collaboration.mpeg download activity. Both were stopped and frozen. I don't know
why. This situation existed about 15 seconds and another error happened.
Download manager first set Alice.zip progress status to Finished, Transfered
size to 81008 KB. Obvious download manager made mistake, because the download
was incomplete and actual download size is about 5M bits not 63488KB. 

I don't know weather it is network data transfer error that cause browser's
Download Manager made such bug. Before I have met the same bug. This time it
recured. So I think it's necessary to tell you, the great development team about
it. Hope this infomation is useful for you.
