Ok - Its a Control whose description includes the word SET. But it is so far 
away from what I wanted that I didn't recognise it (in a VERY fast skip of a 900 
page document) as relevant.

The attached picture compares Gerhard's Control with an array of CheckBoxes. His 
Control gives a good visual indication of which bits are set in a form
that has a pretty good resonance with my application.

I have found a (minor) bug which I can't quite track down.

Suppose, with reference to the attached picture, I have TWO sets of CheckBoxes, 
and 2 Set Controls, all linked to the same SET, and no Guards or Notifiers.

When I toggle some bit with a CheckBox all 4 Controls automatically update. 
However, when I toggle a bit with the Set Control only the Set Controls update,
the CheckBoxes do not until some other event causes then to be redrawn.

I thought the problem was with the way Controls.Notify was being used, but am 
not sure.

Using Notifiers is an easy workaround, but I am interested to understand the 
problem as I suspect that some other Controls I've written may have the same 
problem.
