Azureus 3.0.3.4 on a mac

I'd only tried this for Windoze before, and been disappointed by the Vuze interface, which I still don't like. This time I got it for my mac, because BitRocket has BitRotted after the Jaguar upgrade. Yeah, Java hasn't improved any since I last checked... So depressing. I'm running Firefox, iTunes, a hundred other things, and the one little program that's supposed to sit in the background and download things for me, yeah, that's the one taking up the most memory and CPU time.
