If you're using 3.271 with the CM19A (yes, it works for receive and transmit in 3.271!), and have macros defined as "run on PC" (which you have to do since the CM19A doesn't store anything), when you exit AHP, the macros continue to function (listening for devices, turning things on/off, etc.) as long as you don't manually cancel the X10NETS.exe job! Once you cancel X10NETS.exe, then macros no longer execute.
Not sure whether it did this in previous versions, but I find it VERY interesting! In effect, you're running AHP as a Windows service!
