this addr was toggle open/close the last npc dialog box. so for normal this will useful to move from one area to the other. if u use it for storage or trade dialog then will freeze the game.. not actually freeze (DC) but only freeze the icon so u can unfreeze if u change the icon back to arrow

. need some tracing to client code to use this at storage and trade stuff. i had tried to move char xyz and mapid to the herbalist and open dialog box, but still freeze

. if someone had any clue to do that.. pls share to us.
