Playing single track adds all subsequent to playlist

[junogoose]

When selecting 'Play' for an individual track within the folder listing, it adds itself to the playlist and begins playback... which is fine. Unfortunately it is adding all subsequent tracks in the current folder to the playlist as well.

This occurs with the Play option only. 'Play next' and 'play last' behave normally.

Ver. 5.0 (build 4100)
Windows 7 ultimate

Thanks,

Still no change on this in 5.1 (build 4311), so I figure I'd include some screen captures.
