The reason behind the graphics error on the site on resolutions over 800x600 is because they are using a full 800x600 image as their backdrop. On the bigger resolution monitors, it begins to tile itself (repeat). The solution to this is to have the banner at the top be a seperate image and have the backdrop be something else. (use a frame if you need to do the graphic underneath the navigation links on the left hand side)

Simple fixes. As for whatever statement they're all talking about. I don't care. Nice site, good content. Just a design error. That's all. Gladd I could help
