I have this same problem except that it pertains to worksessions and layout views. When I open a worksession, my detail views in paperspace (existing in the active file) automatically show all layers in the detail.

Plug-in central. Definitely was not happening before Vray and Tsplines, I’m looking at Bongo or Flamingo as the suspect. Im going to look into seeing how to load rhino without the plugins and I will let you know what I find.
All the plugins above were fine. It turned out to be a trial version of Clayoo that was installed. Once that was off, problem solved. My Rhino now opens much faster with the plugins now turned off for general modelling.
Thank you for all the replies, 2 birds with one stone here!
