.....I shall have an inward digest of those facts. I also took a look at the cnet site where they seemed to think that MSE could slow down one's computer, which seems slightly at odds with F-O-R's experience. I suppose I could download it, try it for a bit and if it doesn't seem to suit I can bin it and come back to what I have now. (Hopefully with nothing lost)
