I am using an old iMac g3 or whatever it is, and ive downloaded some programs and when i try to open them, it bounces on the dock and them shrinks and goes away. It has done that with Teamspeak and Mumble which are voice chat programs. Is it not supported? If it werent wouldnt it say it in a message like with another program I downloaded? I am using mac osx version 10.4.11 if that helps at all.
