My computer just did a security update and such, and then required restarting. The last time it happened, as I mentioned on this here site, it took two times restarting to get the keychain "change all" button to appear, and it was really annoying. So, I did a permissions repair, the first I've done in about four months, and that, apparently, fixed it, and I got the change all button as soon as it restarted, which is the way it's supposed to work.
