Has anyone else come across this issue?

We do many of our drawing views with shaded with edges display style. Maybe once a day, I'll open a drawing that I am 100% positive was saved with display style set to shaded with edges, only to find all views on all sheets are changed to just shaded. I can change them back fine, but it's just a pain.

Below are my specs.

Total System Memory - 11.9 GB

This amount of RAM is acceptable for assemblies with greater than 2500 components and parts greater than 1000 features.

The total amount of RAM required is based on the size of the dataset used and other open applications.

Anyone see this or a similar issue?
