Well, DUH! Wish I had known that 15-20 turns ago. Thanks very much.
When all the black dots appeared I guess I just freaked and thought it was a glitch and never even bothered to run the cursor over any of them.
By the way, I thought I was pretty thorough looking through the help documentation. Obviously I completely misunderstood what I was reading or just plain missed it. Any hint where I might find the info?
