Essentially, the 'setCursor' call does not change the cursor unless the mouse
is moved. This happens only on NT.

In this example, Hit the "Start Busy" button to start the busy cursor.
Then take your hand away from the mouse and watch the messages in the console
window. When the program is done sleeping, you will see a "Done Sleeping"
message in the console window, but the hourglass stays. If you now move the
mouse, the hour-glass will change back to a pointer.

import java.awt.*;
import java.awt.event.*;

public class cursortest extends Frame implements WindowListener, ActionListener
{
Button bdat= new Button("Start Busy");
public cursortest()
{

bdat.addActionListener(this);
Panel p = new Panel();
p.setLayout( new BorderLayout() );

add( p );
p.add( "North", bdat );
p.add( "Center", new TextArea( 20, 20 ) );
addWindowListener(this);
}

public void windowClosed(WindowEvent event) {
}

public void windowOpened(WindowEvent event) {
}

public void windowIconified(WindowEvent event) {
}

public void windowDeiconified(WindowEvent event) {
}

public void windowActivated(WindowEvent event) {
}

public void windowDeactivated(WindowEvent event) {
}

public void windowClosing(WindowEvent event) {
System.exit(0);
}

public void actionPerformed( ActionEvent event)
{
Object source = event.getSource();
if ( source == bdat)
{
setCursor( Cursor.getPredefinedCursor( Cursor.WAIT_CURSOR ) );
System.out.println("Starting Sleep for 5 seconds ...");
System.out.println("Remember to remove your hand from the mouse");
try { Thread.sleep(5000); } catch( InterruptedException e ){ }
System.out.println("Done sleeping");
setCursor( Cursor.getPredefinedCursor( Cursor.DEFAULT_CURSOR ) );
}
}

public static void main( String args[] )
{
Frame f = new cursortest();
f.setSize( 200, 200 );
f.show();
}
}


Is this going to be fixed in the next release of jdk(1.1.1)?
Several groups at Cadence cannot release their products without this fix.
