Can anyone explain why when someone is uploading from my system., the upload rate will start about 10 kb/s, then immediately drop to about 1 kb/s, then to 0 kb/s. Few mins later it will start uploading again for few seconds then stop and shows 'complete'. Then maybe start again.

When once connected, why does it not containue to upload until finished, and why does it do it at such at such a low rate. I seldom ever see "100%" complete. When I first got the program, most of my uploads showed "100%" complete.
