thanks so much for the suggestions. The interfacelift site has a ton of awesome icons, thank you for pointing them out.
The problem I'm having is that sometimes when, using Candybar, I change an Icon...it doesn't change on the dock, even when it's relaunched. Even when I change the icon manually (using command-i and copying and pasting the icon) it sometimes doesn't work. For Word, for instance, no icon will paste in. And sometimes I know I changed it, but it just won't change on the dock.
any ideas?
