On a few of my setups, AmIRC seems to have some memory leak bug where it will just start eating all my RAM until it's gone, on a 32MB and a 128MB machine it happens. I wish I knew how to stop it because AmIRC is much faster than WookieChat, although WookieChat is still what I use on my 030 A1200. I use Grapevine on my 2MB 68000 A600 and it works great too.
