I wonder what's grabbing the Alt key there. I've tried, but wasn't able to break Alt-drag. Some more ideas:
Alt+<right click> opens the window menu, which has an unmaximize option
Alt+Shift+<left click&drag> moves the window to snapped positions
Alt+<left click&drag> moves the window (for completeness, not new)
If none work and you haven't done a lot of customization, perhaps try to reset the metacity configuration:
gconftool-2 --recursive-unset /apps/metacity
Careful though, this resets hot-keys and theme to their defaults.
If this fails too, try (temporarily, for testing) replacing Alt with Super, aka left windows key,
gconftool-2 -s /apps/metacity/general/mouse_button_modifier -t string "<Super>"
and see if Super+<right click>, Super+<left click>, Super+Shift+<left click> on Onboard does anything.
