	* gtk/gtkdnd.c (DROP_ABORT_TIME): Changed to 5 min
	from 10 seconds, so it doesn't abort while users
	have an ACTION_ASK menu up.

	* gtk/gtkdnd.c: Hide the icon window between sending a a
	drop event to the destination and displaying the
	snapback animation, so that it doesn't hang around
	during ACTION_ASK.
