Any geometry line, circle,hatch etc.
I can't change the diameter of a circle, hatch or layer.
I can create new geometry and edit it, but anyrhing I did the previous day is a no go.
this is exactly what I assumed to be the reason.
I have seen this that many times, that - of what reason ever - this option was changed to Active Layer only.
I can imagine that is also has happened without interactive input by the user.
Maybe there is a hidden shortcut, a mouse clicking sentence or what ever.
As I sayed, this has been seen for a long time for different versions of SE and with many, many different users.
I believe that it was not Your fault.
