This maybe only a WIn32 phenomena
Where the cursor sometimes disappears and you have to
something like double right click to get it back.

This is a good idea.
My guess is that this wants to be in the actual C Code instead of the XML
script
We could probably do this by having new classes that contain the actual
value
and its acceptable range and then the XML script would point to the
appropriate
C variable.

ie any variable that was settable from a ui of any form would be derived
from
one of these 'super types'.  It could be that a puValue object is a good
base class ?
This is close to what I was alluding to when I suggested an XML inteface to
PUI.

BTW have you noticed the similarity between the getters and setters in
PUI and in the Properties module.

It almost seems as if all we need is a  fgTie( puValue, fgProperty)
or maybe even a fgTie( puObject, fgProperty);

but I am not a properties expert by any means.
