  Steps to Reproduce:

  code below.
  
  import java.awt.Rectangle;
  
  import java.awt.Toolkit;
  
  
  
  import org.eclipse.swt.SWT;
  
  import org.eclipse.swt.SWTError;
  
  import org.eclipse.swt.browser.Browser;
  
  import org.eclipse.swt.browser.LocationEvent;
  
  import org.eclipse.swt.browser.LocationListener;
  
  import org.eclipse.swt.browser.StatusTextEvent;
  
  import org.eclipse.swt.browser.StatusTextListener;
  
  import org.eclipse.swt.graphics.Point;
  
  import org.eclipse.swt.layout.FillLayout;
  
  import org.eclipse.swt.widgets.Display;
  
  import org.eclipse.swt.widgets.Event;
  
  import org.eclipse.swt.widgets.Listener;
  
  import org.eclipse.swt.widgets.Monitor;
  
  import org.eclipse.swt.widgets.Shell;
  
  
  
  
  
  import lotus.domino.*;
  
  public class JavaAgent extends AgentBase {
  
  
  
   void trace(String msg) {
  
    System.out.println(msg);
  
   }
  
  
  
    public void NotesMain() {
  
  
  
     boolean displayLeftToRight = true;
  
    // Construct SWT widgets
  
    Display display = new Display();
  
    // A modal dialog box
  
    int mode = 0;
  
    if (displayLeftToRight) {
  
     mode = SWT.DIALOG_TRIM | SWT.APPLICATION_MODAL | SWT.CENTER;
  
     trace("Display from left to right.");
  
    } else {
  
     mode = SWT.DIALOG_TRIM | SWT.APPLICATION_MODAL | SWT.CENTER
  
       | SWT.RIGHT_TO_LEFT;
  
     trace("Display from right to left.");
  
    }
  
  
  
    final Shell shell = new Shell(display, mode);
  
    shell.setLayout(new FillLayout());
  
    shell.setText("IBM InfoSphere Content Collector");
  
  
  
    // embedded browser
  
    final Browser browser;
  
    try {
  
     browser = new Browser(shell, SWT.NONE);
  
    } catch (SWTError e) {
  
     trace("Could not instantiate Browser: " + e.getMessage());
  
     return;
  
    }
  
  
  
                                shell.setLocation(20,20);
  
    // prevent from moving
  
    final Point location = shell.getLocation();
  
    display.addFilter(SWT.Move, new Listener() {
  
     public void handleEvent(Event arg0) {
  
      if (!shell.getLocation().equals(location)) {
  
       shell.setLocation(location);
  
      }
  
     }
  
    });
  
  
  
    // redirect when detecting offline, only in local replica
  
    browser.addLocationListener(new LocationListener() {
  
  
  
     public void changed(LocationEvent arg0) {
  
      // TODO Auto-generated method stub
  
  
  
     }
  
  
  
     public void changing(LocationEvent arg0) {
  
      // TODO Auto-generated method stub
  
  
  
     }});
  
  
  
    // implement event handling function
  
    browser.addStatusTextListener(new StatusTextListener() {
  
  
  
     public void changed(StatusTextEvent arg0) {
  
      // TODO Auto-generated method stub
  
  
  
     }});
  
  
  
  
  
    String formURL = "www.google.com";
  
    /* Load an HTML document */
  
    // browser.setUrl(URL_ADD_DATA_FORM);
  
    trace("formURL" + formURL);
  
    browser.setUrl(formURL);
  
  
  
    shell.setSize(800, 700);
  
  
  
  
  
    shell.open();
  
    shell.forceActive();
  
    while (!shell.isDisposed()) {
  
     if (!display.readAndDispatch())
  
      display.sleep();
  
    }
  
    display.dispose();
  
  
  
    }
  
  }
  
  
  2.  Set the agent to run on 'On Event', 'Action Menu Selection'
  and Target to
  'None'.  Save & close the agent.
  3.  Open the database from notes client and run the agent
  created in previous
  steps.
  4.  Notice the new window that pops up, if you move it the notes
  client does
  not redraw/refresh.
