/*
If an id is also specified and a window with a matching id has been shown before, the remembered bounds of the window will be used instead.
Size calculation for innerBounds seems to be faulty, app was designed for 960x625
Bug was confirmed on Windows 7
OSX seems to be unaffected
Linux and cros is unknown
I am using arbitrary dimensions which fixes the Windows 7 problem, hopefully it will get resolved in future release so other OSs won't have to
use bigger dimensions by default.
