I originally had Windows XP and just recently reformated to Windows 7 and had to reinstall WoW. And before I uninstalled; ingame i was able to click on a player and/or target and it would select them and then be able to off click on anything tht couldnt be selected and it would drop the target i had before. Since i reinstalled WoW it wont let me do that anymore. I have to hit esc to drop target rather than clicking nothing. Sorry if that doesnt make sense only way i can describe it. I cant find anything in the interface that shows this.
Please help its just a habit of mine off clicking to de-select a target. I heal so i find myself doing it all the time to heal myself by off clicking instead of hitting esc, its just faster to me. Thank you.
