I have the following Hosts entered in Tools > Options > Connections:

router.limewire.com:6346
connect1.gnutellanet.com:6346
through
connect7.gnutellanet.com:6346
gnet2.ath.cx:6346
gnotella.fileflash.com:6346
gnutella-again.hostscache.com:6346

I cannot connect at all. I am using Mac G4
OS 9.1
384 MB RAM
LimeWire 2.4.4

I have not tried for a few days to connect, but as I am reading, this is especially a problem today.

Is it just Mac users having this problem?

And if so, why?

Very strange.
