Thanks all for the tips. The trick of right-clicking on the Back button was a new one on me

I'm aware of the "Index," Main Index", "Next," "Previous" etc links but it's only out of sheer laziness I don't use them more since I resent the need for scrolling to access them. It is usu so much easier just to click on the "Back" button til I get where I want to be

Agreed that tweaking an algorithm is a tedious and thankless job--if not expensive too--and I wouldn't wish it on anybody just to satisfy the whim of a sluggard such as I. I had hoped that my proposal wouldn't be so difficult it performed during a routine upgrade
