I upgraded my two iMacs from Mountain Lion to Mavericks (10.9, Safari 7.0) recently. 1Password (3.8.21) seems to be working except the 1Click icons in the bookmarks bar bring up the correct web page but do NOT enter the userid or password.
Clicking the 1Password icon in the menu bar and then selecting the same site, Wells Fargo bank for example, brings up the page and then DOES enter the userid and password.
I deleted the old bookmarks bar icon and created a new one by dragging from the 1Password app's Logins list Same thing - brings up the page but does NOT enter the login information.
I created a link on the desktop by dragging from the 1Password app's Logins window. Double clicking it brings up the web page and DOES enter the userid and password.
Does a Safari/1Password configuration option somewhere need to be changed to get 1Click bookmarks bar icons to enter the login information?
