Right-Clicking or Order(attacking) an enemy doesnt follow unit around

[tobbygnome]

I would like to know if its posibble to program a map so that when you press attack and select a enemy OR right click an enemy that it doesnt follow the unit around, attacking it where ever it goes, for example when you attack an enemy and the enemy runs away i want the attacking unit to just continue attacking the ground the enemy WAS in @ the time that you issued the attack.

If anyone could help me out it would majorly help me!!
