how do i get lower zone window zoom in / out to mirror the arrange window?

currently if i zoom in or out in the lower zoom, the arrange window does not move and in and to follow it, and id like it too ?

In the Lower Zone toolbar there is a button that looks like 2 links in a chain (you may need to make it visible if you don’t see it). If you enable this it will link the Main & Lower Zones.

thanks - what’s weird is i closed the project and reopened it and then the expected behaviour returned, and i hadn’t touched the linking button, made a bug, not sure

Accidental key command?

could be - likely i made som kind of mistake but i don’t remember doing so, anyway all back to normal. thanks
