This is reproducible with the following simple applet. You do not even
need to select a file, simply hitting "Esc" when the file dialog is
open is sufficient to hang IE7. I strongly suspect there's a problem in
IE with handing focus back to the main window after having had a modal
window.

package test;

import java.applet.Applet;
import java.awt.Button;
import java.awt.Color;
import java.awt.Event;
import java.awt.FileDialog;
import java.awt.Frame;
import java.awt.Panel;
import java.io.File;

public class ModalFileDialogTest extends Applet {

    private static final long serialVersionUID = 1351796453988581417L;

    public ModalFileDialogTest() {
        Panel p = new Panel();
        p.add(new Button("Open"));
        p.setBackground(new Color(255, 255, 255));

        add("North",p);
    }

    public boolean action(Event evt, Object arg) {
        if ("Open".equals(arg)) {
            System.out.println("Opening file selection");

            FileDialog fd = new FileDialog(new Frame());
            fd.setMode(FileDialog.LOAD);
            fd.show();

            String selectedItem = fd.getFile();

            if (selectedItem == null) {
                System.out.println("No file selected");
            }
            else {
                File file = new File(fd.getDirectory() + File.separator +
fd.getFile());
                System.out.println("Selected file: " + file.getName());
            }

            return true;
        }
        else {
            System.out.println("Unexpected arg: "+arg);
            return false;
        }
    }
}
