LightWindow closes when top left corners of child widgets are clicked.

[Dane Henson]

When LightWindow contains a large widget (unable to determine exactly what size this manifests), the widget will contain a spot in the top left corner that will destroy the window when clicked.

This can be seen in lp:agenda-tasks when the top item in the list is checked. It is also evident on the welcome screen, though it is harder to locate.

This happens to me in Agenda.

This happens in Birdie too, when you sign in with your twitter account.

The issue was caused by Gdk.EventButton returning a Gdk.Window of whatever widget that was clicked, containing the relative coordinates of the widget. Fixed by using root coordinates instead.
