    I did use 'el' in several previous iterations of testing, but do not do 
so now, and forgot to remove it. (Will do so  today)

    Also, checked out Safari Version 5.1.7 (7534.57.2) on my dev PC today, 
and it works 'correctly'.

    So that leaves FF as 'odd-man-out' for now. (I haven't got Opera on my 
system because it is not frequently used in North America, and even less 
frequently among my 613 potential clients.)

        Yes, will change this.  Thanks !

    O.K., will use this too.  (but should I not use ""13"" instead ?

    YES

    I use the value of  'gotret' when returning to the 'onkeyup' clause to 
'blur'. Then, the onblur clause operates.

btw, thru my server software I read html templates, build, and send pages to 
clients, access and manipulate databases. I use the Harbour language for 
this (a Hi-C type of language). www.whosaway.com

Next, I will be scratching my head and trying to re-learn AJAX. Used it a 
few years ago successfully. Since then, I've lost a lot of what I knew, and 
what I knew was then incomplete, wrong and now certainly out-of-date.

    I am still bothered that 'onkeyup'  is invisible to FF, whereas the 
three others I tested work for me as Iexpected.

Thanks for all the constructive suggestions above !  Will ensure they are 
implemented as you detailed.
