When you have set Active Desktop to suit your preferences, you can prevent the accidental resizing or moving of items by locking them in place. Right-click a blank space on the Desktop and select Active Desktop. If the Lock Desktop Items listing has a check mark next to it, your desktop can't be edited. But what if you want to edit it later? Right-click a blank space on the Desktop, select Active Desktop, and click Lock Desktop Items to access and remove its check mark.
