I would imagine that it would do the update
check everytime that you run AHP - since it
doesn't keep track of the last time that it
ran. A change of thought here - AHP would
do the check upon starting. X10nets would
be running to keep track of module status -
ON/OFF and if the module is dimmed (NOT the
dim level). It would also update the time
on the CM15A. I don't know what else would
be done.
Unless you have changed Windows settings, I
believe that Windows Update makes the same
type of update checking as well, which
makes sense - it's easier to have your
computer make the check-in rather than
having to notify upteen gazillion users
individually, or make you do the check
manually yourself. A lot of users just
wouldn't do it and not update thier OS.
