(I don\'t want to hear about how crazy I am to want that! :)
Focus-follows-mouse is also known as point-to-focus, pointer focus, and (in some implementations) sloppy
Experimenting with those options, my Command-Tab started to behave oddly. Here is the solution of how it gives focus to apps again:
It appears that a previous feature, namely the ability for Terminal's window focus to change with mouse movement, is broken in 10.6 and causes Command-Tab to not transfer window focus correctly. To fix the problem, just paste the following command in a Terminal:
defaults write com.apple.Terminal FocusFollowsMouse -string NO
Then restart Terminal.
