Comment 3 for bug 990909

This affects me too. I find that if you repeatedly click on maximize, eventually (on the 4th or 5th click), the maximization will "stick". Not ideal, but a "workaround" of sorts :)

I'm slightly concerned that Ubuntu is officially deprecating the notion of "focus follows mouse" and therefore won't fix this. After all, it is not possible to select focus follows without installing the non-standard config-compiz.
