You'll be happy to know that I finally got that script to work in PSElements. It's a long story but for one thing I didn't need to have the script in any particular folder... I could call it up from outside PSE. Secondly, I was using a printout of the 21 step file in the QTR folder, but somehow the script expects the 21 step file that accompanies the script.
Anyway, it works like a charm, thanks so much for reminding of that tool. Like I say, I tried it once a year or two ago but got stuck. This time the good people over at http://www.photoshopelementsandmore.com/ helped me out (good people here, too, I don't mean to imply othewise!).
Thanks to all,
Paul W.
