Crash,
Not totally sure what you're having trouble with. Could you explain better about adding a file? I don't see anything with a "menu."
I'll take a guess and see if this is what you mean:
I have mine set up just like described in the installation instructions to install uTorrent on WHS. I down load my torrent links on one of my host PC's. Then drag them all into the WHS Share folder I set up during installation ...I think the folder I set up is "\\Server\Public\Torrents." Then uTorrent sucks them into the program and the down loads start on their own.
There are other ways to load the torrents into uTorrent, but I found my way to be the easiest for me.....

Also, I rarely use the uTorrent Add-in in WHS Console. I pretty much work using the uTorrent web GUI interface.
