Cart with zero balance - awo coupons

[MBAngel]

After using a gift certificate for a specific product, the cart total is zero.  It still asks for a credit card.

I found this post... http://forum.virtuemart.net/index.php?topic=105264.msg365709#msg365709 that explains how to set up a 2nd payment module, and says to enable automatic payment selection.  I set the authorize.net payment module to min value .02 and I set the 'VM - Payment, Standard'
to .000001.  Both are published. 

I'm wondering if this is because the products aren't free, just the end total is free, and vm is not checking the total, but the fact that an item in the cart has a price.  Is there something broke here, or is there somewhere I can edit the cirteria?

Authorize payment method? You could try standard payment method instead.

lol, I did...  I have to have authorize.net for the payments..  I set up the standard one for the gift certificate pruchaes that end up with a zero balance...  as I said in my post...  But when I go to checkout with a zero balance..  it still shows me the authorize..net payment module...
