I am experiencing layout paperspace views randomly changing and or disappearing. Is there a way to lock these views similiar to locking a viewport? The views that I am having trouble with are views I create by "attaching a document" from a group into our border templates. For the life of me, I can find no way to lock these views, tabs, layou tabs, paperspace, blocks, whatever you want to call them. it would seem a simple task.....someway to prevent inadverntly / accidently changing your work. I know of the lock / unlock dimension option, but that doesnt work either. I keep finding info on locking viewports, but by adding these drawings to our border as blocks does not create a viewport....
