When you say "open pop-up" do you mean:
- rightclick red mark on the border
- Select "suppress" in the menu shown
That does not work for me, the pop-up menu that is shown when right-clicking is completely different and is the same independent of where in the left border I click. It has 13 items to select from starting with "Toggle Breakpoint".
Seems not related to the problem we are discussing.
I am on Sloeber 4.2 and I know there is a newer version available, could this be something new in a newer Sloeber?
Unfortunately I did not dare upgrade because the description on how to do it was so incredibly difficult to follow and I stayed with the "working" version...
