I think everyone with a MS Fingerprint Reader on Vista has this problem. You lock the workstation by pressing Windows key + L (not Switch User, just Win + L), and when you touch the fingerprint reader to log back in, it says its not you. So to log back in, you click Switch User and then touch the reader and it lets you log in. Is there a fix to this? Will Vista SP1 fix this? The Microsoft Fingerprint Reader even says its Vista certified. By the time it switches user I could have typed in the password. Websites are fine though.
