Display style choice = no choice

I have a drawing with 7 views, anything from detailed views, iso view, section view, cropped zoomed in view etc....

They all respond as they should except for the fact that I cropped view has a peculiarity. I can only see it when I put in one of the shaded styles. If I select any another style then those two it makes it viewable for 0.5 seconds and disappears. After awhile, while editing other views I'm able to make it stay viewable in a not-shaded viewstyle until the next time that I load the drawing when I can fiddle with it all over again.

Oh, and it isn't just that it isn't viewable but that particular view isn't printable either when it's misbehaving.

Is this a known issue ?
