Remember though that this will only be triggered with the main window is
displayed, so the pointer will be unavailable prior to this.  This
temporal coupling may be a problem and you should be aware of it.

Also, if you are using libglade make sure you upgrade to the latest
version, as older versions didn't support the map event (strange but
true), which caused much scratching of head and weird pondering when I
tried to use it last :).
