I'm on a G4 running OS 9.2 ... when adjusting options, you can't as the radio buttons, sliders are off to the right from the options window, there is no resizing the window to get to them ... limewire is a piece of **** programming wise, how could they expect me to want to buy the pro version? get the free version working well and i'll definitely pitch in for the pro ... p.s.:napster worked ****ing well, limewire has so much crap no one needs!!!
