Hi Remus,

had the same in my app, when i forgot to uninit a running browser before 
calling the method BrowserControlFactory.appTerminate(), like it is done in 
the example application of ed.

I implemented a method, which is called, when a window is closed:

  private void shutdown(){
    browserCanvas.setVisible(false);
    BrowserControlFactory.deleteBrowserControl(browserControl);
    browserControl = null;
    browserCanvas = null;
    currentPage = null;
    bookmarks = null;
  }

Since that time its ok

Best, Michael
