Description Sven Gothel 2013-12-04 07:31:22 CET 
For an unknown reason, on Windows w/ Java7, a NewtCanvasAWT's NEWT window
will not receive a sent key-release event by AWT Robot while otherwise being IDLE.

It is observed that moving the mouse a bit, i.e. sending other events down the 
AWT/Native event dispatcher removes the 'clog' and the key-release event is dispatched.

The 'clog' happens to be _before_ NEWT's Windows native event queue's dispatch path,
since the key-release event was not visible here before moving the mouse.

Remedy as observed: Inject tiny mouse-move events ..

  Fixed as described (move mouse back/forth)
