        Just to clarify, I noticed someone bring up the interrupt in a previous
message and so didn't think I would be off topic for replying to it and asking
a question about it.  Apologies if I was wrong.

        But in any event, the program is causing quite a slowdown in other apps
which is what drew my attention to it.  I normally do not run Pulse because of
it's somewhat subjective display.
