+    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.
