24 hours ago I successfully moved some photos from All Documents to Trash. Suddenly my next attempt resulted in a popup window "Preparing to move to Trash": this window has remained onscreen since then. My only option on this window is to click stop, & now each file I have there runs with "Stopping..." And of course no further items have been able to be moved to Trash. Attempts to empty files from Trash result in the message "cannot delete files from Trash as currently files are being moved to Trash." Please help me escape from the clutches of this dilemma. Thanks.
