Terry,

I've noticed a strange thing on this forum. It could just be my browser (firefox), but or it could be a bug in the server software. What happens is occasionally a post will cause the server or the browser to get confused. For example, on your post above, the one that started:
"DA. I've just worked out how I can explain it all to Trilobyte: "

Notice that we are on page 3, but page 3 was not displaying - it just came up blank. I could tell there WAS a page 3, I just couldn't see anything on it when I clicked the link. This has happened previously, but very infrequently. I have discovered that if I just make another post to that thread, then the "lost post" shows up, followed by my "bump check."
