DOpus lister window title bar suddenly colorized?

Hello bonjour,

I had my lister windows title bar color set similar to the Operations toolbar below (dark grey) and haven't changed any color settings recently. Somehow it turned blueish in the last day or so.

Preferences open = shows correct set color


Preferences closed (or File selected in the Lister or click Lister window while preferences open) = blueish title toolbar


Has something changed recently? How can I switch this back off?

Thanks!
