Overlapping Macros?

[PajamaGuy]

This morning while a delayed macro had continued and was resetting the light scheme in my house, I KeyChain armed the DS7000.  The system armed, but the arming activity was not logged in the activity monitor. 

Question:  While a macro is executing, and its steps are being recorded in the activity monitor, is it normal for other activities (like arming) to not get recorded?  If so, are there any guidelines?

Based upon my logs it seems that multiple macros can be firing simultaneously - so it begs another question:  If an RF command (like keychain-arm) doesn't get recorded, do the target AHP switches/macros/modules get tripped?  Is there (should there be) a incoming buffer?

Thanks!
