Another thing that I noticed is that........The "First Name" and "Last Name" information in the "Contact Information / Personal Infomation" area do not get populated into the "First Name" and "Last Name" fields under the "Billing Address" and "Shipping Address" section. Even if the customer has the option "Same as billing address" checked during registration.
Hopefully this minor bug will be fixed in the next beta release.
