A while back, Chase changed to the TLS 1.2 protocol, but still (apparently) allows the weak SHA1 and the RC4 cipher in their connection negotiations. I'm frankly not sure whether Olde Opera is capable of communicating with the combinations now offered by Chase, or whether the Chase cert even points Opera in the right direction. Moreover, there's always that old bug-a-boo: browser sniffing, that can cause all manner of grief because of whatever their site code does with it.
