Cart-input field

Hi.
Install com_hikashop_starter_1.4.5_2011-02-19
Strange bug, input box appears, which I can not remove...

from HTML:
<input type="submit" class="button hikashop_cart_input_button" name="refresh" value="Add" onclick="return hikashopCheckCoupon('hikashop_checkout_coupon_input');"/>
this....
<input id="hikashop_product_quantity_field_2" type="hidden" value="1" class="hikashop_product_quantity_field" name="quantity" />
....

You need to edit the file cart of the view product via the menu Display->Views and change the line:
$this->params->set('show_quantity_field', -1);
to:
$this->params->set('show_quantity_field', 0);

That will be fixed in next version.
