 * Changes 11 Jan 2003 Anthony Roy:
 *
 * 1) Changed checkText from a JTextArea to a JTextField (lines 51 and 115)
 * 2) Altered the ADD_CMD action (Line 196). Now adds the misspelled word to the dictionary unless
 *    a new word is typed which does not match the current suggestion. A confirm dialog is shown.
