The version the Alpha testers are running behaves exactly the same in terms of gapless playback as Beta 13. The current beta you've got doesn't insert any gaps between two tracks. The player software is currently doing all it can do. If you can't make the files gapless, the problem is in your MP3 files, not in the player software. Have you read the last stuff I put into the FAQ on this topic? I thought it was reasonably current.
