Photoshop Elements 2021 panel won't dock
Basically, the title says it all.
I have just upgraded from 14 to 2021 and now I can't get my panel with Navigator, Info etc to dock at the side. It will dock next to the Layers panel, but that takes up far too much additional screen space.
When I drag there is no blue bar except when it allows me to drop it as above.
Any suggestions?
