You're not alone with this problem; I've
seen the same thing myself (and reported it,
and I assume X10 is working it). In my case,
at least, even when the CM15A 'starts
working' again after replugging the USB,
it's not reliable (sometimes macros will
trigger, sometimes they won't). Something
in the software (or in the CM15A firmware,
which doesn't get updated with new releases
of AHP) has gone askew.
Whether or not its related to the activity
monitor buffer or not is an open question.
My activity monitor starts showing 'bogus'
entries (that contain text relating to REC,
PAUSE, TV-- items that in no way relate to
any kind of timer or macro that I've
defined. I assume that this text is buried
somewhere in the AHP program and is being
dumped into the activity log by a pointer
thats gotten overwritten or in some other
way corrupted.
