I can't click on the tile option when changing my desktop background?
I decided to change my desktop image and when I clicked on the drop down box thing to change it from center to tile, tile was there, but it was faded away and I can't click on it. I tried doing this with 3 other images and it wont work. The images are all .jpg, perhaps that is the problem? I am using Mountain Lion by the way =) Thanks
