macro repeats continuously

[rocket]

I have a simple macro to turn on a lamp. Right now, that's the only step in it. When activated by an X10 ON command, the macro keeps sending the same ON command ever couple of seconds.

Does the lamp and the macro have the same house & unit code?

The macro and lamp are on different house and unit codes.

Please post all the steps in the macro.
Any motion detectors on the same codes? Any on nearby codes. e.g. Motion detector on B1 and macro on B2.
Do you have any models, real or not, programmed to the same code as the macro?
Clearing the CM15A and downloading again may solve the problem. This would only make a difference if there were a "ghost module" or some other glitch in the CM15A.
