i apologize as well.
yes, indeed, Broker_CPU seems to have changed its behavior (as of 40000.19, released 2010/01/04). however, note that my original post was dated 2009/12/27 (at which time there was definitely something not right). i would also note that Mera's original post in this thread did not really clarify anything one way or the other...
anyway, i updated Broker_CPU when the new version was released, but did not know to re-test it (there had been no response to my thread at that point). i also did not remember (days later) that it had been updated the week before, so did not re-test to see if the problem still existed. i just saw starlon's post and acted on it extemporaneously (by disabling Broker_CPU, which seemed to have the desired effect
).
just tried again, and can confirm that whatever problem existed previously definitely no longer exists. AddonProfiler now seems to co-exist very happily with Broker_CPU.
again, i apologize.
