Unity opens application menu on Alt+F10 shortcut

Menu is also triggered after pressing Alt+F7, moving the window and pressing Enter to finish moving.

Alt+F10 doesn't maximise the window for me at all, neither does it open a menu. Are you using the default settings of Unity? unity --reset will restore the default settings for Unity. Marking as incomplete pending some feedback.

Did "unity --reset" on a fully updated Natty system.

Alt+F10 maximizes currently focused window AND triggers the application menu.
Alt+F7 moves currently focused window and triggers the menu, after pressing Enter (ending window movement).
Alt+F8 also opens the menu, after the resizing operation is finished by pressing Enter.

Thanks for updating. This also happens if you alt+Tab and then press Esc to cancel it. Seems like compiz is pushing keycodes around ....
