Ah, yes. But just because I leave the backplotter up doesn't mean I'm
running. I get the slowdown even if I just run the program once and then
leave backplot active. The effect is not absolutely repeatable. Sometime
it slows down and sometimes not. But I don't think that absolves
backplot. I never get the slowdown if backplot is not running. 

Sorry I cannot offer more light.
