i disagree. using names in ur macros will make sure u can never swich chars around. if u use focus u can use whatever char u want. without using names.
I think the intention was to show the simplest possible setup to help the OP with his problem rather than to start yet another discussion of why focus is such a bad system for assigning a "master"

Tiffer, with regard to your movement problem:

I'm not sure what you're alluding to with the comment on using the mouse to help with movement, so I'll ignore that. Post a more detailed description of what you mean if you think the problem lies there.

Have you unbound the movement keys from your clone, or at least added them to the blacklist to make sure they don't get sent over? Check your auto-run button too - that can cause some comic effects if you've forgotten to unbind / blacklist it on your drones.

If you just get this happening occasionally, and apparently randomly, then it's a phenomenon known around here as "the runaways". It's random, has no known reproducible cause and no known cure other than to keep an eye on all your characters and hit a movement key or follow macro to get them back under control when it happens!
