OK, I found the problem, and solution: Searching for documentation, I found the following note:
You don't need to add the popup to the RootPanel or anywhere else. If you do, "Results May Be Unpredictable" (wich was IBM's way of saying that they didn't know what the **** would happen). So removing the statements to add the popup to the root panel, solved the problem. Per -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
