Hi, thanks for the quick response.

The version is as follows:

Band-in-a-Box® for Windows
Version 2025 (1128)
64 bit application

Returning to factory settings made no difference, but I tried something else, and actually solved it.

The file I was using was created with an older version of BIAB (2022), so I copied the chords to a new .SGU, and now the bar highlight is synchronized with the playback, so that's an adequate solution.

Not sure what would have caused it, and I have a few hundred .SGUs that were made with BIAB 2022, so if there's a better solution it would be helpful.

Thanks again though.
