To answer Dwight Knoll's query about root threads for OpenBase: this is normal if you have StickyBrain, which uses OpenBase as its back-end database. There may be other applications which also use OpenBase. On my laptop (Mac OS X 10.4.5 with StickyBrain 3.6.0, which is a little out of date) I have processes for OpenBase, openexec, openinfo and openmonitor, all owned by root.
