It uses plugin module overlibmws_iframe.js to prevent obscuring of overlib popups for
IE v5.5 or higher via an iframe shim (as opposed to iframe content). For the other
supported browsers, plugin module overlibmws_hide.js also is imported and its
HIDESELECTBOXES and HIDEBYIDNS4 commands are used to hide and restore the form element

The window.createPopup method was developed by Microsoft for creating popup windows with
DHTML functionality but not subject to being obscured by any form elements or by objects
with system controls. The method is restricted to IE v5.5 or higher. The
overlibmws_iframe.js plugin module is equally effective for overlib popups, but has the
same browser and version restriction.
