enter_notify_event and leave_notify_event signals

[Tim Flechtner <timf trdlnk com>]

hi everyone,
 i would like to receive the enter notfy event and leave notify event 
signals even when the mouse is moved into/out of a widget while a mouse 
button is down.  anecdotal evidence shows me that only when the mouse 
button is released do i get these signals, beyond the leave notify event 
in the widget i pressed the mouse button down in.  i suspect this has 
something to do with the drag/drop signals (which i have no experience 
with), as the GdkEventCrossing pointer supplied by these signals has its 
mode set to GDK_CROSSING_GRAB when i leave the first widget, and 
GDK_CROSSING_UNGRAB when i release the mouse button.  does anyone know 
of a way i can get the enter and leave event signals regardless of any 
mouse buttons currently down?

thanks!
