Units not attacking my designated target?

In quest mode, I am trying to get my units to either move from their position or attack a different target than what they currently are. When I right click they continue to attack the closest target. Is there a setting I have to change for this? Note: I'm not clicking the "Attack Move" button.|||yea this problem is retarded.. they need to add a "passive" button or something, so frustrating trying to micro units that wan't to attack something else.|||getting some problem, units sometimes "go crazy" and don't respond me, attacking their targets like mad and don't want to move or attack other target, that sucks!|||This issue wasn't in beta... its stupid it exists now.
