I agree on the Trillian thing HP, it solved a lot of problems for me.
There are settings to change your icons to large size in there too Peaches, I'm just too beat to give you the paths since Id have to look for it to tell you.
I love XP, I haven't rebooted in 33 days at this point and I don't have a memory bleed or any other problem with it. Lots and lots of standby time on it too
