I'll have to try this. 
On projects with say, 20 tracks I set the channels to "Narrow" while mixing so I can see them all. 
When I open the project again it's all gone. 
I've save this view as my default lens ( Advanced) but it makes no difference. So I will try the locking after I set a project.

How do you lock the screenset, BJ?
