PayPal IPN - Website Payments Standard

Does anyone know why the memo field is not display in the admin panel after a PayPal payment? The information is stored in the database but never displayed which means a customer could leave a message which the shop owner cannot respond to. How can this be included in future Zen Cart releases?

admin > customers > orders > invoice or packing slip has these comments

Check

admin > config > shipping > Display Order Comments on Admin Invoice
admin > config > shipping > Display Order Comments on Admin Packing Slip

Are not set to off

They are set to display order comments in my shop, but i thought this meant comments the customer included in the zen cart checkout.

I meant the comments the customer can include when in the PayPal payment process. These are returned to zen cart and are in fact stored in the database. However paypal_admin_notification.php does not use or display the data.

(I should add that I fixed the deficiency by modifying paypal_admin_notification.php but I feel it should be included in a future release of zen cart)

Can you please post the fix?
