If the a message notification is created at the same time as the system tray icon is embedded it may start at a wrong location, since the icon location it bases its own location is not yet final. This patch adds code to update the balloon tip location when the system tray icon is moved or resized. The bug and fix can be tested by the systray example by disabling the icon and letting show message trigger both showing it and the message.
