Dan,

There are a couple of things that I have seen causing the white screen problem.

1. Make sure you have the latest "patch" of G2 downloaded from the control panel.
2. Try turning off fog from the menu bar.

The white screen problems are usually caused by how your graphics card handles the fog that G2 tries to display. As far as I know, the patches fixed problems for most video cards and you can turn it off if your particular card still does not work.

Good luck.

Carl
