Thanks,
NZSharkbait; I'll get back when I get around to implementing & applying your thoughts & insights (life's survival priorities keep getting in the way..) Bye the way, SaveGames is full, RichSavedGames is empty.
I delete the saves by going to the in-game save screen, highlighting the save and clicking on the Delete button at the bottom. I don't think the load screen gives the option to delete.
