without looking into it too deeply i can say there's a number of sites (including this one) where user and password saving isn't working currently, and your bank may well be one of them. Also, don't hesitate to report bugs to us even if they're WebKit bugs! It's good to be able to have a record of what's wrong, so we can watch for a fix, or even write one & submit it to the WebKit team ourselves!
