I just purchased the new macbook pro 13.3" with Leopard installed. The problem is, even if i have selected "keep arrange" selection by kind, I can't seem to find the "auto arrange" selection? Whenever I drag something to the desktop, it doesn't automatically align to the grid, it goes to where i dragged it. I want to be able to drag it and arrange itself to the grid automatically. Could someone please help? it's really annoying.
