Robin, many thanks. It is clear to me that I should be getting the pop up as shown in your second image, but it just isn't happening. everything else works fine, just not anything to do with the editor. I am really inclined to just give up now as I have been trying for five days and it just gets more and more frustrating each time it doesn't work.

Robin, you're a star! The one thing that was different in your images from my game was that you are in windows view, whereas I was in full screen. I changed to windowed view and hey presto! A pop up screen allowing me to choose my data base files appeared.
Many thanks, you have saved another soul
Chris
