Hi. Don`t know if it is a bug of Opera or HFS or some wrong option that i set...
Tested on 2.2f and 2.3 beta Build #274
I`ve got Opera 11.01, Windows XP
I start the download, then interrupt it (stopping server, kicking connection or stopping in browser), and when i resume, it seems that HFS continues as if it resumes and Opera starts as if it downloads anew. And after resuming target file doesn`t change in size, as if after resuming Opera sends data to some mythical /dev/null
Firefox handles pause and resuming normally, but if you kick connection or stop server, it thinks that file is fully downloaded o_O
