So this is my first post here on Mac Forums. Hello everyone. O.K. My problem is that I want to change my Desktop picture, so I go to System Preferences then to Desktop & Screen Savers. That all works fine up until I try going through the different pictures, and the scrolling gets choppy and then I get the little "loading" emblem thingy, and it just stays like. I sat there waiting for 15 minutes then I just force quit the program. I have tried restarting my mac and it does it again. It works just fine with every other option things in System preferences and only freezes when I got to Desktop & Screen Savers. Now the other day I was online and right clicked on an image and selected "Use Image as Desktop Picture" that was working fine but I wanted to go back to my original image so I did what I just said in the paragraph above. Even though I can't change my image through System Preferences I can still do the "Use Image as Desktop Image" if it is an image that is online. I am wondering if I can fix this or if I need to go to the Genius Bar at the Apple store (which I don't really want to do). Also any Ideas on why it is all of a sudden doing this, I have had this mac for like 3 weeks and before I could go through the desktops with breeze. PLEASE HELP!!!!!
