Still not working in some projects. I am sat here desperately tapping away to try to rename a folder, there is no alternative way either, unlike editing tracks where you can hit return. Wasting my life away double clicking!"
Yippee - Found a way round it. You can single click in the inspector folder name instead - that works
It seems NI Replika may have a hand in the unreliable double clicking, out of interest, do you have it installed? Taking it out of projects here has made a difference though time will tell.
