Well, I *think* I'm using 70.2.

It is.

No, cmdCancel, cmdApply and cmdSaveAndExit are children of ConfigureWindow as 
they are the same routines on every "page" of the tab control.  No sense
repeating the controls.

I have plenty of other controls that fill the bill of being children of the
tbi's.

I agree that is the desired affect.

That doesn't work for me.

Thanks for point that out.  It works as advertised. And a byproduct is that the
other issue is fixed at the same time and only the controls on the specific tab
selected are visible.  I knew that the "accepted" way of doing this would make it
work.  And it does.

That demo works as expected on my machine.  However, since I'm using the IDE to
generate the code file, I wouldn't be able to easily make changes that aren't
contemplated by the IDE.  I mean, I *can* do it and occasionally I generate the
code file and reorder things so that all references are good, but I usually go
back later and figure out how to tweak the IDE so that it is not necessary to do
this on a "final".

Thanks again.
