Controls and scrollbar for Macro Designer Message Output Not Always Visible

When opening the message box output it looks like this.

If you right click on the Program Slot and click on ‘Revert to Last Saved Program’, the controls appear.

On this screen cap you can see the scroll bar is also not visible even though the output is longer than the box.
Scrolling with the mouse wheel does work, but you can never reach the bottom. Leads me to believe the initial message box section is oversized,
causing the controls to hide underneath the window next tot it.
