core uc file is working properly... i think paypal is the hang up here

it would be nice if i could get paypal wps successful transaction reponse to 1. automatically update the order status to "complete" and 2. have the cart cleared

maybe someone's done this or is doing it? ...before i go tear things apart and put it back together such that looks like it's working on the surface but is actually hosed up (that's what usually happens when i start hacking)
