I just took the latest 1PW update (Version 3.7.0 (build 31083) ) for Safari 5.1 for a spin and am very impressed with the progress that AgileBits has made...well done! Everything works as well or even better than with Safari 5.0 except for one thing. Previously you could open the 1PW application, under Logins scroll to a website, click on the URL, be taken to the website and automatically logged in. Although clicking on the URL takes you to the website, only the Username is entered, not the password. So you have to click on the 1PW toolbar button to complete the login.
Will that feature be updated to work as it used to? I certainly hope that is the case.
Thanks again for all of your efforts for this Mac Gem of a program and keep up the good work!
