Okay, so I've made a few homemade icons using Preview, and I'm happy with the results but I can't click on them when they are on the Desktop. They are clickable when in any window, but when placed on the actual desktop the icon itself isn't selectable. The title and the "alias arrow" are selectable but not the image.
Example here
Notice it the icon with the title "Class Notes".
Can anyone help me out here?
