I've tried Virtual Moon Atlas on two Vista Home Premium laptops and it
has problems on both.

All 3.5 versions except Lite suffer the same problems.

Laptop A suffers the same exit crash problem as described in these
ostings.

Laptop B suffers with access violation exception errors and the moon
graphic does not show.

I've tried applying the recommended fixes but neither of them work.

I'm glad I did not purchase the CD!

The problem here clearly is OpenGL support. This is known to be poor
under Vista anyway and seems to be supported by the fact that Redshift
5 and 6 suffer problems when OpenGL support is enabled too.

It may be better to drop OpnGL support altogether or at least have the
option to turn it of in all versions of the product.
