There is nothing to do except design them at that size. I still design all my forms at 800x600. They can, of course, be resized by the user to something larger, but not smaller. As Greg Green said, you can't really design them at 800x600. You can go up to 790 or 800 wide (assuming someone doesn't put the Windows task bar on the side of the screen, which I rarely see), but you can only go about 450 high, which takes into account the VFP menu, a toolbar, the Windows task bar, etc.
