Clicks are captured when another window is on top of the game window

[Wiiseguy]

This can be reproduced in any of the Myra.Samples.*.exe:

• Open any Myra sample app
• Open another app (i.e. notepad.exe)
• Move the Notepad window so it covers half of a button in the Myra sample app
• Hover your mouse in Notepad around where the button is, the hover state of the button is triggered = NOK-ish
• Click in Notepad on the part that obscures the Myra sample app button, the click event is triggered = NOK
