Correct Quantity

[guest*]

Standard the quantity of presta product administration is 1. Where can I change this ? I have standard = 0, also for combinations.
Soe I want when I have add a new product that there ist 0 by default quantity and not 1.

Change line 1425 of admin/tabs/AdminProducts.php from:

$qty = 1;

to:

$qty = 0;
