[Glade-users] pointer_motion, button_press, etc. not working

[gregh object-craft com au (Greg Hamilton)]

In reply to my own question, if the motion_notify_event handler calls 
event.window.get_pointer() to get the x,y position of the mouse and the 
buttons state then the events keep occurring. If, as I was doing, you 
just print a debug message and don't bother grabbing that information 
the event only happens once.

Odd.
