Options menu > Work Environment > Enable all informational messages...
If that command isn't in your Options menu, due to your own customization, then temporarily use the standard work environment, or add the command to your menus.
It seems a strange place to have that command to me... and not obvious that 'informational messages' would include the Start dialog. Just the messenger...
