Presumably you're using Internet Explorer...which has "issues" showing HTML elements over other objects on the page that are rendered natively by the OS (iframes, flash, select boxes, etc).
To get around this "limitation", GWT utilizes a hack where you put an iframe shim behind the popup panel's contents so the shim iframe obscures the other one. See the code in PopupImplIE6 for how its used - there's also a link in the code to a blog posting w/ a fuller explanation.
