I think you have the camera too close for one thing, the orthographic type
really always should have the 'up' and 'right' keywords in there to specify
the scene dimensions. Of course the default should make for a 4/3 wide by 1
high view, so the objects not appearing whole or not at all must be related
to the close proximity is going to be my guess anyway, without actually
rendering and testing.
Well, I just can't resist trying it out.  Tried it.  Nothing wrong with any
of the four viewpoints.  What version POV-you have there?  I used 3.1g for
Win.
