I'm using 10.5 right now, on an iMac G5. My problem is with where an icon 'lands' on the desktop when I move it about. The second column from the left is where I have trouble dropping items. Each time I try to do so it snaps to the wrong column, normally the one on the left. This isn't a problem when I reduce the grid size for desktop to a smaller size (I have it at the largest). Is this a known bug? And does anyone know a fix for it?
