build 20020124

I get an internal error when I search for write access to the variable 'toggle' 
in the class below.
I'm going to upload the workspace to walleye /va2000/INCOMING/forKnut in case 
you can't reproduce. The class is in project Playgound_Knut, 
kr.PR.FlashTest.java.

import org.eclipse.swt.*;
import org.eclipse.swt.graphics.*;
import org.eclipse.swt.widgets.*;

public class FlashTest {
	boolean toggle = false;
	
public void create() {
	final Shell shell = new Shell();
	Display display = shell.getDisplay();
	final Canvas canvas = new Canvas(shell, SWT.NO_BACKGROUND);
	final Color background = new Color(display, 222, 222, 222);
	final Color color1 = new Color(display, 0, 0, 0);
	final Color color2 = new Color(display, 222, 0, 0);
	
	canvas.setSize(200, 200);
	canvas.addListener(SWT.Paint, new Listener() {
		public void handleEvent(Event e) {
			if (toggle) {
//				e.gc.setBackground(color1);
				e.gc.setForeground(color1);
			}
			else {
//				e.gc.setBackground(color2);
				e.gc.setForeground(color2);
			}
			e.gc.setBackground(background);
			e.gc.fillRectangle(e.getBounds());
			for (int i = 0; i < canvas.getSize().y; i += 14) {
				e.gc.drawText("FlashTest Line FlashTest " + i, 
0, i);
			}
		}
	});
	canvas.addListener(SWT.KeyDown, new Listener() {
		public void handleEvent(Event e) {
			toggle = !toggle;
			canvas.redraw();
		}
	});
	shell.open();
	while (!shell.isDisposed ()) {
		if (!display.readAndDispatch ()) display.sleep ();
	}
}
public static void main(String[] args) {
	FlashTest test = new FlashTest();
	test.create();
}
}
