Umm.... shades of pondering that come back to haunt me. I hang my head
in shame to remember I once expected this to be someone else's
responsibility.....

If you have for example say:

integer txt_Total

	txt_Total=3D3
--[1]
	...
	txt_Total=3D5
--[2]
	...
	txt_Total=3D7
--[3]

You cannot (would not and do not) expect an "event" to be generated at
points [1], [2], and [3].  You quite obviously just code it yourself.

The point is, anywhere you do a setText() or similar, you must have
all the code to handle the changes *your* program just made, sorry.

Embarrassingly obvious once you think it through
