I’m not able to add markers on V1.920, the context menu shows the option when I right click but nothing happens. Any one else got this issue or is it just me?

Hi @SimonA, is it possible you have both left and right traces showing? When both traces are active, markers can’t be set due to the fact that there’s not a way to associate the marker with a particular trace.

Yes, I had two traces up. I can now place markers by hiding a trace. Thanks.
