+// This Dialog class implements a pop-up dialog. This is needed because
+// apparently you can't use the standard AWT Dialog from within an applet. The
+// dialog can be made visible by calling its showDialog() method. Dialogs can
+// be modal or non-modal. For a modal dialog box, the showDialog() method must
+// be called from a thread other than the GUI thread, and it only returns when
+// the dialog box has been dismissed. For a non-modal dialog box, the
+// showDialog() method returns immediately.
