PPT-11  The Hidden versus Visible attribute

Tip:

While it isn't obvious there is an important difference in
using the HIDDEN or VISIBLE attribute.  The hidden attribute
can be used to control the Implicit behavior of a widget.  This
means setting widget a:hidden = false does not cause the frame
that contains the widget to come into view.  The setting of the
visible attribute a:visible = true does bring the parent frame
etc. into view.

Wisdom:

Beware the simple, first assumptions when going to debug a
program.
