Forgive a noobies question, but I just started multi boxing today, and my eyes are tired and I could be missing this information.

I've gotten through all the basics, gotten keyclone and set it up, and everything's good there. All I'm trying to do is improve gameplay, and thank you very much all of you people that got me to this step.

I've played WoW for quite some time, but have never really been able to level a pally, mage, or priest for some reason or another. So I've decided to multi box with those three classes. I'm currently using the pally as a main, with the two casters sittin back and casting. However, I'm wondering if I can get the casters to STOP following my pally once they're in range of whatever spell I'm spamming as I close in on them.

In a nutshell..
1) Check to see if mob (using pally as focus)is in range
2) If mob is in range, stop moving and start casting.

I don't mind spamming this as I approach the mob, I'm just hoping there's a macro condition I don't know about that will be able to do this for me. Thanks in advance for the help, and sorry again for the poor english. My only excuse is extreme fatigue.
