bobsboy confirmed via PM that this still occurs with 1829.

I've been able to replicate--tracked at: http://www.ventismedia.com/mantis/view.php?id=14037

Thanks bobsboy!

Could you please try whether the same issue happens with 1827 ?
It might be related to this regression in 1828: http://www.ventismedia.com/mantis/view.php?id=14036

The latest version of MM (4.1.15.1828) would not play when Jammix Enhancer plugin is enabled. Selected tracks would only jump to the next track, and then the next, until the last track in the playlist without playing any.

Disabling, then enabling Jammix, does not resolve the problem. MM would only play if Jammix is disabled totally.

Kindly find a fix to enable use of this plugin again.
