Bugfix for v0.912
The bug causes the product_type not to be set when clicking on a "Edit product" link in the admin notes notifier. And if product_type is not set when using the Zen Cart products editor to save the product, it will change the products_type to 0, which is not a desired value!

To fix it open admin\includes\init_includes\init_notes_notifier.php

and change:
Code:
products_type
to:
Code:
product_type
