Model shading issues
I had a glitch with my wireless mouse on my computer which caused it to erratically move my cursor and click. After I got my mouse disconnected and my computer back under control, all the faces on all my models seem to be permanently stuck in something that looks like the shaded curvature view, with seemingly no way to get the shading back to normal. There is also intermittently a black screen that replaces the entire view window.
How can I get back to my default view settings? I tried resetting everything to default in options -> System Appearance, but this does not fix the problem. I am running Creo 10
