When I mouse-over on Orzo's Excellent Wand, empty pouch slot is visible over my dwarven warrior char. My human wizard is behind the warrior.
and mouse-over on a staff item also triggers the pop-up for the staff slot. Seems like mouse-over isnt checking for active character sheet... Hope it helps.
Not limited to arcane items either...My priest is on the 3rd sheet and mouse-overs divine items also throw up the slot name. Seems like its got smthg to do with last char sheets and mouseover, prolly incorrect array pointers somewhere? Hope it helps.
