I'm getting frustrated with this, if anyone can help I'd appreciate it. I'm using a MacBook Pro (Penryn) running Leopard. Every time I try and change my wallpaper in system preferences, it crashes and asks me if I'd like to report it to Apple. It eventually gave me the "would you like to reset settings and relaunch" dialogue. Still continuously crashes. Help! I just want to change my damn wallpaper and this is annoying me to no end. Thanks in advance.
