2002-03-04  Jeffrey Stedfast  <fejj@ximian.com>

	* folder-browser.c (my_folder_browser_init): Connect to the
	focus-in/out events on the message-list so that we can disable the
	EditInvertSelection and EditSelectThread menu items when the
	message-list is not in focus.

	* folder-browser-ui.c (folder_browser_ui_message_list_unfocus):
	New function to de-sensitize some items if the message-list is not
	in focus.
	(folder_browser_ui_message_list_focus): New function to sensitize
	some items if the message-list is not in focus.

	* mail-callbacks.c (invert_selection): Only invert the selection
	of the message-list if it is the widget in focus.

	* message-list.c (message_list_select): Do not explicitly grab the
	focus here.
