OK, so usually I get this mail:

Problem occurred while customer #xxx -- username -- was attempting checkout. (Classis 15005 error)


Then some of my customers told me they got a mail from their bank cause they think the shop is a fraud (I guess cause they try to checkout multiple times).

I couldn't reproduce this error, but according to 2 of my customers Zen doesn't say what's wrong, it just redirected them from payer_auth_frame to checkout_payment again.

It would be great if I could parse the 15005 on the payer_auth_frame and open a popup so the user actually knows what has happened.
