Hi Pat.

Have you tried going to ACTION - TEST AUDIO PERFORMANCE ? It might be useful to see what the theoretical track count is showing.

One of the things that I've noticed is that using sub-groups is very processor intensive. Could it be something like that?

EDIT - Do you have the CPU usage indicator displayed on the toolbar. That would tell you if it's a processor problem.
