Minimise/maximise window key shortcut problem

[uzi3k]

When I use the windows key plus cursor up/down to maximise and minimise a window, the keyboard shortcut display always comes up and then the only way to get get back to it is to tap the windows key to open the dash, and then tap again to close the dash to return to the original window I was trying to maximise or minimise.

Just to clarify, the maximise or minimise does work it's just obscured by the keyboard shortcut display.
