This should be simple, but I can't figure it out.  Nor can google.  So
I need some help.

I have a form with various controls - including a couple of text boxs
I want to use for collecting date information from users.  The
textboxes are located near the top of the form.  Below the text boxes
are several listboxes that will display information based upon user
input, to include the dates entered into the text boxes.

In order to constrain the date input, I am using the Calendar Control
11.0.  On clicking in the text box, the calendar pops up.  As the user
clicks a date, the date is entered into the textbox and the calendar
disappears.

All of my controls have a tab control as the parent.

The issue here is the listbox zorder.  I cannot seem to push it into
the background.  When the calendar component pops up, part of it is
obscured by the listbox.  As a matter of fact, I cannot get any other
control on the interface to sit on top of the listbox.

So the question is: how can the listbox be moved backward in the
zorder - in design view or programmatically?

This is a bit vexing, as the listbox seems to have its own
'personality' when it comes to this rather conventional task of form
layout.

All help is appreciated.
