Make sure you have your movement keys for the main on the do not pass list for the software emulator. That way when you hit "w" only the main moves forward.

Also, I dont know if it would help in your situation or not, but I have my follow macro set to the "w" key on the alts. That way whenever I move the main the alts are constantly being told to "follow" the main as well. It seems to help me so that I dont have to hit a follow macro key then worry about moving.
