Found in GWT Release: 1.4 RC

Detailed description:
I was using a trick to cause PopupPanels to fade in by setting their
visibility to false, calling show, and then using scriptaculous to fade
them in.  In 1.4 RC this now results in an error.

Workaround if you have one:
None as of yet, still investigating

I get the same error when simply trying to show a popup panel.

In FireFox, it works fine. In IE6, I get "Error: '__frame.style' is null or not an 
object.

This worked fine in 1.3.

Clarification: It fails when I call:

    popup.setVisible(true);
    popup.show();

Not when I just call popup.show();

Comment 6 by gwt.team.rdayal, Jun 12, 2007

This issue is also related to the problem of having to call show() before center()
when  centering a Popup. The result is a "jumpiness" effect.

Another problem has to do with the initial Popup position causing a browser window's
scrollbars to flash whenever a Popup is initially shown.

Here is a link to the thread describing these issues:

http://groups.google.com/group/Google-Web-Toolkit-Contributors/browse_thread/thread/23ee5bd6237dd6b/60c286e78ee8d212

We'll take care of these additional problems as part of this defect.
