WLM+ runs at about 27K for me, and awhile ago I was looking around at other clients like MirandaIM. They all failed. However, Sk8 pointed me to Trillian, and it ran at about 20K with a nice look to it. After fooling with settings, I found a way to remove the TextDresser bar and had made it run at about 8K
*just smiles and nods* Yes Serpy
Yay, another who is nuts about RAM!
8k, really? *Goes off and downloads*Ya, a few nuisances with it but none call for denial
Plus my new WinXP skin makes blinking hard to see
