page keys odd in Pprune!
 

when I do Pprune on my desktop PC, Win Vista, Firefox etc, I find that the page up and page down keys don't do what they should in forums. The function of these keys varies depending upon where on the page the cursor has been clicked to, if a click has been made on the page. The Home and End keys don't do anything. I think it is a "forms" issue but I can't figure out how/what is happening.

On my laptop PC, Win XP, Firefox etc, all of the keys do what they should irrespective of where the cursor is positioned.

Any suggestions will be gratefully tried.
