A4 viz graph is "black" (win32 only)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run A4E on win32
2. Visualize an A4 instance
3. The A4 graph pane is black

What is the expected output? What do you see instead?
The A4 graph pane should show the A4 instance graph

What version of the product are you using? On what operating system?
0.1.7 from SVN

Please provide any additional information below.
With 64-bit linux (ubuntu 7.0.4) and RSA 7.0.0.3,
A4E works fine A4/SAT4J.

I recently started using A4E on win32 where I experienced this problem.
The article below suggests a simple fix
Fix is 
http://www.eclipse.org/articles/article.php?file=Article-Swing-SWT-Integration/i
ndex.html

In A4E's case, applying this article suggests the following changes:

public class MultiPageEditor extends MultiPageEditorPart implements
IResourceChangeListener{

    /**
     * @author Nicolas.Rouquette@jpl.nasa.gov
     * @per Reducing Flicker
     * @see

ndex.html
     */
    static {
        if (Platform.OS_WIN32.equals(Platform.getOS())) {
            System.setProperty("sun.awt.noerasebackground", "true");
        }
    }

...

    /**
     * Creates page 2 of the multi-page editor,
     * which contains a frame with the graph.

     */
    void createPage2() {

                IEditorInput input;
                input=editor.getEditorInput();

                Composite swtAwtComponent = new Composite(getContainer(),
SWT.EMBEDDED | SWT.NO_BACKGROUND);
                java.awt.Frame frame = SWT_AWT.new_Frame(swtAwtComponent );

                /**

                 */
                javax.swing.JApplet applet = new javax.swing.JApplet();
                frame.add(applet);

                javax.swing.JPanel panel = new JPanel();

                MyVizGUI viz = new MyVizGUI();
                viz.run(MyVizGUI.evs_loadInstanceForcefully,
Util.getFileLocation((IResource)input.getAdapter(IResource.class)));

                panel=viz.getGraphPanel();
                if (panel!=null)
                    applet.add(panel);  

                FillLayout layout = new FillLayout();
                swtAwtComponent.setLayout(layout);

                int index = addPage(swtAwtComponent);

Antoine, Francois,

I am not using A4E under windows. Could you try the reproduce the bug and 
confirm
that behavior?

Nicolas,

Could you provide us the exact version of the JVM and Eclipse you are using?

Windows with Eclipse 3.3.

With the 3.3.0 Eclipse (lastest version) and the 0.1.6 A4E i don't have any bug 
with
graph viz.
I'll try more checking tonight.
