Great, thank you. I've changed the validation code as per your suggestion and
everything seems to be working fine now; I had been under the mistaken
impression that these methods were always the right ones to call when checking
the text that *could* be changed, so I had changed many references to
-selectedRange to use these methods - which explains why I only got bug reports
about accents in recent versions.
Thanks again and all the best,
Keith
