Hi Jim,
Sorry to hear that you ran into this bug.
We need more info though. Please tell us:
You say "It tries to maximize, but simply performs a maximize on that display." What do you mean by this? See bug 551 for what I experienced, I have a screenshot. If you are experiencing a different problem, please provide a screenshot if you can.
What are the details of your system and monitors? See bug #551 for the details I provided.
What exact settings do you have set for the sesion? See bug #551 for the details I provided.
Note that I filed bug #551, rather than replying to this bug report, because I wasn't sure if it was the same bug or not.
