Oh! Indeed, now I see this!
I never noticed this behaviour!
Probably because I always work with the transport bar open.
As I mostly prefer to work with a separate editor (I find the editor in the lower zone most of the time too small for my needs) I may then return to the way I am used to work and renounce to the transport bar in the lower zone, though I find that this is a quite nice feature.
But to always have to close a “double” transport bar each time you work in an editor and use the locators is not really an elegant way to work.
Anyhow thanks for your thoughts.
After trying to go back and use the floating transport bar, I notice now that in the arrange window I can’t use the locators shortkeys as it always was before Cubase 9. In order to work the focus has to be on the floating transport bar!
It means you have now to first click on the floating transport bar if you want to use the shortkeys!
This should definitively not behave this way.
