When I call

   dialog --title "Title" --msgbox "Hi there" 7 40

then the displayed image is not
+---------- Title -----------+
|         Hi there           |
|                            |
|                            |
+----------------------------+
|          <  OK  >          |
+----------------------------+

(as it was in Red Hat 6.2), but instead it now looks like

+---------Hi there ----------+
|                            |
|                            |
|                            |
+----------------------------+
|          <  OK  >          |
+----------------------------+

(You might get a better impression with a monospaced-font)
