I can reproduce what CrissJJ reports although I would expect all tracks to be highlighted (neither last nor first alone, but all).
As related to bug 4830 I understand that MediaMonkey should no longer retain the individual track selection history, but the node history like pre 3.1. Do I understand Rusty's note incorrect or is that not fixed in 1212.
Yes--the current behaviour (in which the 'back'/'forward' buttons retain a history of individual tracks within a node) is unexpected.
e.g.
-Click an Artist A
-Click another Artist B
-Click 3 different tracks within Artist B
-Press 'Back'
-->MM currently switches to the second Track by Artist B, but the user would expect that MM would switch back to Artist A.
