Not to second guess you, but if that snap shot was immediately after you hit 6 in the front view, it didn't work. Your perspective view is highlighted which means your cursor was hovering over the perspective view when you hit 6. Other than that, I'm clueless. I have 8.5 and no problems with image planes.
Don't be satisfied with what you can do but rather strive to do the things you can't do!
