I solved this for Us using 4.0.6
One step in /include/func.php

1)between flag and details add notes , position does matter

payment_method, flag, notes, details, 

2)at the bottom, add

 '".addslashes($order_details)."'  

just before '".addslashes(text_crypt($order_details))."',
Step 2) will add details to notes before it gets encryped. This will populate notes regardles of payment type.
It seems to work for us.

cut-and-past this code below in place of orig. code
