MusicBee Version: 3.4.7592
I created 3 tabs:
Tab 1:Album Covers (show the tracks for the selected album at the bottom of the main panel)
Tab 2:Album Covers (show the tracks for the selected album to the right of the main panel)
Tab 3:Playlists
If you switch back and forth between Tab 1 and 2, everything is fine.
The tracks are always displayed correctly in the lower part or on the right.
However, if you switch to Tab 3 (Playlists) and then back to Tab 1 or Tab 2, the tracks are neither displayed below nor on the right in the main panel!
