what if you put the command on the actual button as apose to the system macro? Not that you dont know how to but here is how I would try
1. Create the button,or select the hard button I wanted. 2.Right click 3.Edit properties. 4.rs-232 5.enter the string 6. Select sustain. 7.Delay between repeats = 0.0
Just a guess.
Don't read my answer. Someone else will go into great detail as to why I am wrong rather than answer the original question...
