title: Me.undo to prevent changes when closing a form
body: <p>I want to use the <code>ME.UNDO</code> command to prevent changes when closing a form in Access 2013.</p>
  <p>I have a form that links to a table which contains a worklist. This form is read-only to prevent accidental changes.</p>
  <p>To make changes, the user needs to double-click an item to bring up another form, which is related to this particular work item, then make changes on it.<br />
  I have a save button for the user to click to save the changes. If the user just <strong>closes</strong> this form, I do <strong>not</strong> want to save the changes.</p>
  <p>I am using <code>me.undo</code> in the close event (and this is the only code line in that event). It is still saving the change in the worklist form.</p>
