I'm trying to create a popup window using PopUpManager and a
TitleWindow that will cover the entire application. In other words,
I'm looking to have a 100% width x 100% height. Unfortuntely, this
doesn't seem to be working - only absolute widths/heights seem to
That is not surprising. Popups are not exactly rooted within
the application, so relative sizing will not work. Try getting the
application size form the width/height properties at run time and
setting the popup size accordingly.
