I have 2 toons that I play and I have noticed a difference (problem) between the two.

When I play my Cleric and I equip a healing stick (cure wand). I then hit the F1, F2 etc. key to target. Then I hit the attack (Left click) button to heal the corrisponding targeted player.

When I play my Rouge (who has high UMD) I equip the wand like normal. I then hit the approprate F key to target the player. I then click the attack button (left click). Instead of healing the targeted player my Rogue throws a punch. I have to click on the hotbar repeatedly to activate the wand.

Why the difference? Can if fix this problem.
