I've been following along with this forum for about a year now and thankfully haven't had any show stopping problems to ask about up until recently.
For a few months I have been plagued with an issue in that when I open a new sketch on a part, for example, the whole part will turn black and I need to switch to wireframe view, back to shaded and it will fix the problem, until I close the sketch, etc. Rebuilding doesn't work most of the time.
The issue I've been dealing with right now affects the planes I've added to the part. When I open a sketch, the planes turn black, and I have to switch to shaded view, back to wireframe to be able to see what I'm working on. Here's a picture of the planes black.
