Hi Yuri,

The getLocationOnScreen() method is executed synchronously on all 
platforms. Since the invokeAndWait() version is used to query location 
there is no need in any extra waiting for the location value.

I inserted delay before the location request because the window may not 
be shown yet or its final dimensions may not be established. Window 
showing is asynchronous and can takes significant time on some platforms.
