Strange that. I'm not sure why you are getting those results. Although already quite sure of what would happen, I just did a test: I put an audio event on a track, trimmed it (by picking the edge up and moving it sideways; or by using the trim tool - it made no difference), and then used D to duplicate the trimmed event multiple times. No problems - the trimmed event was copied exactly; and I didn't need to bounce it either. Sorry I can't help you with your issue other than to confirm expected results in my case. Cheers.
