A4 Alarm: More Data Points

See below message I received this morning.  I, too, did get it to go off
this morning, with the windows down.  I opened my garage and it didn't go
off.  I stuck my arm in twice and the second time I snapped my fingers andit
went off.  I think the snapping was a coincidence.  When I piece all of this
information together, it tells me the sensors will not notice motion low in
the window, but if something breaks the plane higher up, it goes off.

I know for fact it is not noise (the manual specifically states the sensors
do not monitor the glass/windows).
