Create a checklist and call one of the *printw() functions from the

Browse Source 
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 =).
