Has anyone experienced working on a part file and suddenly find that the solid body becomes completely invisible on the screen but still exists and is "shown" not hidden?  If I roll up and down in the feature tree sometimes I can get it to reappear, other times I toggle the hide/show option on the body to get it to display, and other times it just will not display anymore.  The oddest thing of it all is that I can still select faces on the model and highlight the edges, but I can't see anything else. 

Support has not proved helpful with this.  I was just curious if anyone else was having this issue.

Thanks for the help.
