If changing the repeats doesn't help, try putting a "Stop Macro" (I think that's what it's called, I'm not near my computer), or a .1 second delay after the command. This was tech support's solution for me once when a random command seemed to not want to end. I can't remember what product it was for. The idea is to put something after the command to stop the echo so to speak.
