I don't think it's a bug, most likely a progaming goof. They forgot to include "Timer" in the Activity Monitor, so it defaults to "Macro".
If they can figger out why AHP won't correctly show the status of two Lamp Modules on A1 and A3, but correctly shows the status of Lamp Modules (and assorted two-way modules) on two other hosuecodes I use I'll be happy. That's the only problem I currently have.
