my project keeps reverting to 'unsaved layer state'

[davesec]

i have a little layering system i set up. in my drawing, in modelspace (or on any of my sheets), there's a little drop-down box that saves 'unsaved layer state'. if i click on it, i can find my 'personal layer state', select it, and all my layers pop up. but then if i switch tabs for a second, it goes right back to 'unsaved layer state'. how do i keep this on my own personal one?!
