title: creating popup screen on windows mobile 6.5
body: <p>I'm very new to creating windows mobile applications.
  I have a button called 'Settings'- i want this to open a small popup that overlaps the current window with purely a textbox asking for a password.
  How would I go about this? Do I have to create a new form, but size the form accoringly?</p>
  
  <p>I've created a new form and sized it much smaller, but when it opens, it is full screen.</p>
  
  <p>Any help appreaciated</p>
