Why does the Editor open random folders in Project at startup?

Each time I launch Unity, it randomly opens some folders in the Project window. It never keeps the same view as what I had when it was last closed down. It seems to be random, with different folders opening each time.

Is there an option to preserve Project view or similar?
Or is this a bug?
Are you seeing this behavior too?

I’m on Unity 5.3.4.


Apparently, 5.3.5 keeps in memory what folders were open in the project window when we closed it last time; at least it does for me.

I don’t know about 5.3.4. Sorry.

You you get any warnings / errors in the console? When a warning or error is displayed in the console, the source script is “pinged” which will expand all folders to that asset.
