Similar to the previous comment - 1.21 won't launch. I can't test the "opening torrents" because this version won't launch. I have been using 1.06 for a couple of months now and it has been working well - other than a couple of small glitches...

Transmission is also a great alternative for DL single or small files instead of opening up Azureus... although Azureus has other features - Transmission has provided enough to make it contender ... until this version.

I went back to 1.06 today - and 1.06 is working fine...
