DOPPELBOCK  I've gone back to to 1.75 as well. Since upgrading to 1.76 I noticed that active torrents were not showing up on my account on the tracker and were appearing/disappearing seemingly randomly.  
(Version 1.76)

DOPPELBOCK  Thanks for the update for 10.6 compatibility - I'm downloading now to give it a try. I've only had SL installed for a couple days and I miss my MenuMeters!  
(Version 1.4b1)

DOPPELBOCK  I purchased the 50% off license for SecretBook users. I like what app4mac have done with the interface and the export/import of my SecretBook data was simple and worked perfectly.

Yeah, I can certainly agree that it is not really a necessary upgrade as SecretBook was/does still work just fine, but with free upgrades in the future I thought I'd support the developers future plans for the app.  
(Version 1.1.1)

DOPPELBOCK  First of all, the "upgrade" is half price for Secretbook users. Secondly, it's not like the version of Secretbook you have has stopped working has it? You don't have to pay anything if you don't want to.  
(Version 1.0)

DOPPELBOCK  It's obvious who the "fan boy" is.

I've tried this app - each version - and I *still* get better/faster results with Transmission and I like its interface a *lot* more. That doesn't mean I won't keep an eye on this app and see how it progresses though - I've no vested interest in any torrent app, I just want what works best for me and right now that is Transmission.
