small issue with registration

[ruilong]

During customer registration when the customer writes his name, the delivery adress gets autofilled by a javascript, however, there should be some kind of onblur function on this also, since when I do testing, I often fill out this quickly and let firefox/ie autofill the name fields by clicking tab on the "preselected" value with the result that my delivery adress name fields gets filled with one or two letters only

I know that this is because I am registering fast and furious during testing but I can guess that one or two customers would do the same.
