I had never considered the relationship between starting address and the size of the window. I had always just assumed that as long as the size of all the windows created was valid (including the CS0 windows remaining after CS1-CS4 assignments) that I had a happy bus. Time for a design review! Thanks again, Have a great day...&lt;br /&gt;
