If I change my wallpaper (10.7.4), it only changes in the space I'm currently working in.
Is there an option to change the wallpaper on all of the spaces at once, not just whichever "desktop" I'm in when I make the change?
I like to keep different apps in different desktops.
I don't think there is such an option.
You could perhaps delete all desktops, change the remaining desktop to the background you wish, then when you create desktops they should have the same background.
It's probably easier to just change the wallpaper on each desktop than to delete and recreate each one.
