The Problem
 I have a JComboBox displayed in a Panel container that is embedded in a Frame window. When I select the down arrow to make a popup window appear in order to change the selection within the entryfield, the popup window appears to be clipped. In fact, when I do some further investigation, I notice that the popup, which lists the choices to select from, appears behind the Frame component. Is this a z-order problem?
