Lately I've been having a problem with the "Top View" in my scenes showing nothing.  I'll try and set my view to "Top View" and I'll get an empty blue screen and it'll say "top view 0%" in the corner.   There's no grid, no scene, no nothing.
Sometimes I can get around this by using View --> selection and it'll zoom down to whatever I have selected, but this doesn't always work.  Sometimes it stays empty with the 0% view.
Is this happening to anyone else?  I have the latest version on Carrara pro 8 64-bit and am running vista.
Thanks!

By the way, it's also starting to happen to some of the side views (right or left).
