Crossfades don't export smootly

Hi everyone,

I've got a large multi-track edit of a pipe organ recording. We've edited the piece with cross-fading different takes to make one succinct song. I've found though that once I'm satisfied with my cross-fades, they don't always playback smoothly in a consistent manner. I've found also that they don't export well. When I play a two-track mix of the piece for CD, the edits either don't play smoothly or they have little clicks and pops in them.

Is it a latency issue? Any suggestions as to how to get these to export and play smoothly?

Your immediate assistance is greatly appreciated as we need to get a master out quickly for an event.

If it helps, here's a screenshot of the edit (using Soundtrack Pro 2.02):
