right, that is what I'd assume too. use gesttings to flick the various values and check if that's what they're being reset to. plus, with any bug it's usually good to reproduce in a plain X session without a DE running to rule the desktop environments out. the above are exactly the 6 that gnome-settings-daemon supports, albeit the GUI has been mostly an exercise in frustration so far.
