I inadvertently locked a small segment of a trace. Not I cannot seem to unlock it.
To unlock a regular component I select it in the schematic then unlock it in the pcb editor. I’ve tried to select different traces on the schematic but no go.
In the bottom right of the PCB editor window, there are a series of check boxes labeled “Selection Filter”. If you check the box for “Locked Items” you should be able to select your locked segment.
I ran into the same problem when I locked a track and this is a much nicer way of solving this than what I did to get rid of it (I used a text editor to remove ‘locked’ from the segment declaration in the .pcb file).
Somehow I managed to never notice the bottom right selection filter settings as I always used the right-click-select. I learn something new every time I use this great product. Time for another donation!
