yeah that was the problem I think, I was foolishly using it straight off the card reader - and changed flash cards over not thinking anything much about it - but still writing the report from the opened file. So when it went to autosave a while later it couldnt find the card and had a fit - losing everything at 2am after loads of work. It takes a while to go through results and photos to jog ones memory. Oh well.
Yeah bathy tonight would be great
