Some time ago I said I couldn't see pictures Ian Young posted of the troughs he made. I thought they were dark. Such was not the case however, and today I have discovered why. When I bought my current computer I didn't replace the screen as the old one I had seemed fine. But it must have been fading and I hadn't noticed. Today, a whole new internet world is in clear view with a new (to me) flat screen that fellow forumist Sue Gill no longer needs. Not just Ian's pictures, but all the pictures are so much brighter and easy to see now. So apologies to Ian et al, I'll look at that thread again now!
