Well I'm on a G4 2x450's 384mb ram with 56k dial up. Limewire would not hang up connecting so much but I could never get a download connection so I abandoned it for the Furi client. Furi does freeze while establishing a host connection but once connected performs adequately. Mabe give it a try. Also I keep my host connections to three only no more. The third searches for a new host when one craps out keeping two at all times. My only issue is slow connectivity and upload download rates overall, but that is not a client based issue entirely and has to do more with other users and their connections. Good luck.
