Actually I do use FL_RETURN CHANGED... but it is not enough alone.
Because.. FL_RETURN_CHANGED does not get the call-back called when you
press a button. I did play with FL_RETURN_ALWAYS, and with a major re-design
might have been able to make it work but there are problems where the format
of the input needs to be validated once complete and there are problems if the
call back would cause the object called from it to be updated - (keeping
cursors in the right place etc) especially with multiline objects.
It would be possible to be "more organised" and do this (but heck, this is a
free app written for utility and fun - not my day job ;-), but in the end
it was easier to add the handlers to make button presses flush the last input
object if it was "dirty".

I know you and TC are good.. but not even you can manage that ;-)
No.. what I'd like is that after typing some text into an input object,
I get the same callback behavior from that input object whether the next
object I hit is a button or another input object.
Thats the behavior I now get with the handlers I have and I'm quite
happy about the world.. And all the stuff I do now goes through the standard
xforms API. The only complaint I had was that the xforms behavior was rather
counter-intuitive (to me anyway). I don't remember this problem in Motif,
but that was a long time ago and it may be that I just never hit it.
