i'm using the new 2.6.3 and i'm still having that same problem.   
the only difference from the initial post is I am using Win ME (Austin Road Runner Cable modem service) and have a zonealarm firewall, allthou i never receive any warnings from it about these attempted downloads.  I also can upload and download thru other progs, without a problem with this firewalll but i am not ruling it out..   
One thing tho, once, for about 2 seconds I saw an upload of about 1.2 kb/s  then it was gone again.  All of my options are set as mentioned above in the "upload" options menu.
