Could you also put a "never ask again" checkbox in the "Install tcfix" dialog? I do not allow anything to install into /usr/bin unless it is from Apple. Therefore I copied tcfix to /usr/local/bin, yet ThemeChanger still asks. I could do it myself and send a patch if you would like.

BTW, I just thought I'd let you know that ThemeChanger has been referenced on the macosx-dev@omnigroup mailing list as a perfect example of by-the-book AuthorizationServices example code. Nice job on that.
