For some unknown reason this still wasn't fixed in solidworks 2016. Although on new drawing this rarely happens if at all. I opened some old drawing (I think it was sw2011 version) and I had the "view dissapearing" problem. Common problem when drawing automatically changes views to "draft quality". Once you click "high quality" the views dissapear and i can't bring them back unless I change display state to "shaded with edges" - that brings back option to choose high or draft quality and it sets views to draft quality.
I saved all documents to new version and the problem still presists. If I copy/paste views to new document, it's still the same problem. What could cause that? Because the assembly is pretty small compared to other that I've done in the past.
