Open Navigator by clicking Tabs

[TheUnknownWombat]

Hello,

i have a little problem with the Tabs-Toolbar. I recently reinstalled MusicBee after i set up Windows 10.
Previously it was possible to open the left Navigator-Panel, simply by clicking on one of the Tabs. As of now, this only works by clicking on the icon on the bottom left, nothing happens, when i click one of the Tabs.
Is there some option in the preferences that I've missed? Or has this been changed in an updated Version?

Thanks in advance.
