3565	"""External Panelize"" dialog should use WListbox's change notification."	mooffie		"Currently it uses a MSG_POST_KEY/MSG_FOCUS hack to achieve this.

Advantage:

We'll get rid of a subtle mouse bug. The use of MSG_FOCUS in the hack inadvertently makes clicking the mouse update the command. But MSG_FOCUS is actually fired before the listbox changes its item, so the command seen is the __previously__ selected (you don't always notice this because WListbox's mouse handler uses MOU_REPEAT, which makes the problem sometime fix itself after a fraction of a second).
