- Checked the tracks, all are MIDI, none are frozen
- Changed a chord in the song from G to A and replayed the song. Still no "hold" on the aforementioned G... chord but it did play the A instead of G. I assume that indicated the song hasn't been rendered.

I also saved the song to a thumb drive, then loaded and played it (same BIAB version) but running Win XP. Same result.

Thanks Matt!
Any other suggestions?
