Subject: src/ephy-link-action.c

2005-10-25  Philip Langdale  <philipl@mail.utexas.edu>

	* src/ephy-link-action.c
	* src/ephy-link-action.h:
	(proxy_button_release_event_cb), (proxy_drag_begin_cb),
	(ephy_link_action_connect_proxy),
	(ephy_link_action_disconnect_proxy),
	(ephy_link_action_class_init), (ephy_link_action_init):

	Fix bug #319529. Don't activate the action on a middle mouse
	button release event if the release is linked to a DnD.

	This requires adding state to the action to allow us to link
	the drag-begin event to the button-release event.
