Brief
We have updated the 'order_items.php' file for release 3.5.

Taxes were not calculated correctly when administrator updated order's items which included prices with taxes.
 
Solution.
We would recommend you to download an updated version of the file from here: http://www.viart.com/downloads/order_items-3.5.zip
