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.
