Hello Basj,
I have selected "No Never", "On mouseover" and finally "Always". Each time, I don't see the lock/unlock fuction:
Honestly, when I have installed Fences4, all the fences were locked and impossible to move.
After one hour, I have found an unlock function (but unfortunatly it's impossible to me to know I did). A this moment, the fences were unlocked and I have moved them without issues.
Now, I try to find again this lock/unlock function and I am not enable to find... .
BR,
Michel
