Merci, GPFrance:-) (Which has more-or-less exhausted my French vocabulary.) Yup, I've been looking at that area, and a couple of others. I'm beginning to get a glimmering of what I have to do. The trouble is, every time I get an improvement in one area, I get a new problem somewhere else (isn't it always the way?) But I'm working on it:-)) Cheers, Diolma
