Window.KeyEvent

[sage]

Hi guys,
It seems that Window.KeyEvent works wrong under latest WinAos.
Key releasing events occurs as it should be, and 0 bit in flags equal to 1, telling that it's the key release event.
But, it's impossible to know what actually the key was released, because in that case ucs is always equal 0 and keysym is always equal 16777215
See attached project, press some arrow keys.

The bug exists also under A2 native  
Investigating the I386.Keyboard.Mod I've discovered that Keyboard.Keyboard.HandleInterrupt wrongly handles key releasing events. The only useful information that it sends as message is flags field, other fields are nulled (ch set to 0X and keysym set to Inputs.ksNil).
