New Revision: 211731

Log:
  Create a checklist and call one of the *printw() functions from the
  selected() callback. When the dialog first appears, you will not see
  the printed statement on the dialog, if you move down one, you will,
  move up again and it now appears. I am assuming that you call a
  *printw() function on a line in the dialog box of course.
  
  The fix, from the pr:
  	This is a hack at best, I looked at the redraw code in
  	dialog_checklist() and took the minimal amount of it out to do
  	a simple "refresh" right after the items are drawn. This
  	doesn't hurt anything and makes the library work like it
  	should. There is probably a better way however =).
