Maximized windows can still be moved via the deskguide. Doing so seems to confuse sawfish, as windows still behave like they're maximized. Yes, they _are_ still maximized, but it's a bit odd having a big, immovable window occluding the Panel. There are ways around this, but in any case it doesn't seem like correct behavior to me. This bug can also be reproduced with vertically/horizontally maximized windows as well.
Sawfish should constrain configure requests for maximized windows. Upstream as http://bugzilla.eazel.com/show_bug.cgi?id=8410 Closing here
