How do I drag an item to the Trash without deleting it?
In all previous OSs I've been able drag items to the Trash, or select an item and press Command-Delete to move it to the Trash WITHOUT deleting it. That is, the item would be moved to the Trash can, the Trash icon would then appear to "have something inside it," and that item or items could remain there indefinitely, be moved out of the Trash or even returned to their original location if "undone" immediately.
Currently, on my iMac running Lion, either dragging an item to the Trash, or selecting the item and choosing Command-Delete, results in this message: "Are you sure you want to delete [name of item]? This item will be deleted immediately. You can't undo this action."
I've looked for a Trash Can preference to change this behavior and searched Help and the Knowledge base and found nothing I can do to alter this behavior. Perhaps there's a Finder plist or Trash Can plist that needs to be deleted?
