Credit and many thanks to Zeke for mentioning this.
The "Load Game, Continue a Previous Game" action in the Intro screen is in the same position as the "Send game to recycle bin" action in the 'load saved game' screen. This unfortunately can lead to games being deleted by an accidental double click on "Load Game". I have done this many times.
Click on the upper part of the DVD icon of the "Load Game" action in the Intro screen. On entering the saved games screen the mouse is over the "Send game to recycle bin" action. An additional accidental click will delete the first saved game.
