No Track Pictures Browser

The track pictures browser are supposed to open when you double click in the lower left area of the track list. Nothing happens here?
Any clou?

click in the area where the track picture would go, and select “Show Track Pictures” from the menu

that should do it

Well, it doesn’t work with a track where there are no picture already. Tracks that have a picture works!

I did mean to type “right click”, to see the options come up
