I just upgraded to the latest build of Eclipse (3.4) and downloaded the current stable build of WindowDesigner. I then exported my project from my old Eclipse and imported it to the new one.

Any ideas? None of my code modifies the window display on run -- I don't create fields, change sizes, alter layouts, etc. I am using only the generated code to handle the creation of visual object.
