cant change desktop background since the update
Hi everyone,
I got weird problem. Ever since the update, I cant change the desktop background, but if I restart, the new image will show up. I dont know how to get it back to where it was. It used to change right away once I pick a new image but now it will only change after restarting. Can anyone help. Thanks.
