Have seen this sort of thing, not really related to Logic per se. In fact, make sure you haven't left Safari running in the background minimized or something like that. I've seen it eat up the entire cpu cycles when it gets to a bad web page. Try going to Finder->Applications->Utilities->Activity Monitor in Monitor, pick cmd-1 (Monitor->show activity monitor) in the Monitor window, in top drop-down window, pick "All Processes" Then select the %CPU column heading to sort by CPU usage on-down and see if something's eating up your cpu cycles. Could show Logic, could show midi server, could show anything at the top. Can't tell you what to do about it a priori, but that might give you a hint or two as to what's actually competing for cpu resources, if that is in fact the problem. Also, check out Applications->Utilities->System Profiler and select "Logs" in the left-hand menu. Console log and System Log may also give some hints, though they probably wont tell you much about what to do about it either. Phil
