[FX.php List] Visual cue when processing a long, multi-record edit request?

Thank you so much, Steve and Kevin!

It took me a while to get it to work, because I found out that if the  
<div> is longer than can fit in one browser window (which my form  
certainly is), it doesn't hide well.  (In Firefox, I can see the  
processingNow <div> if I scroll up after submitting, but in Safari it  
doesn't work at all -- it only worked when I removed enough table  
rows to see the whole form fit within the browser window, otherwise  
the form just stayed displayed as normal, and only via clicking the  
Back button after processing could I see the processingNow <div>.)

So instead of hiding the whole form, I'm just hiding the Submit/ 
Cancel buttons, and displaying my "processing..." message in their  
place, which is still great and provides just what I was looking for.

Thanks again.
