I have version 4.1.8 on a PowerMac G4 running OS 10.3.5. I have two concerns:

1)Attempts to quit just minimize the window onto my dock. I must force quit everytime.

2) There seem to never be any uploads.

I have a router with NAT, but I opened the port specified (3643 I think) and also opened same port on OS X firewall.

Any ideas or suggestions?
