Issue: Double-click the bar line Doesn't show dialog


I am trying to edit as manual say a bar line. However, when I double click according to the manual Double-click the bar line should show dialog.

I am in page mode and tried different modifier keys. The only it works which is not trivial is to hide the bar handles, then right click and select properties!

Any ideas why double click doesn’t work?

I think what is the issue! I wish this was in the manual!

The Keyboard input was turned on! I don’t know why both MIDI input and Keyboard input can be turned on at the same time.
