To begin with: same OS on both Macs, latest version of OS X. Same version of 1Password 3.9.6. Same version of 1Password Safari Extension, 3.9.9
I have saved the log in data for http://forum.agilebits.com in the 1Password.app.
When I use the 1Password.app and attempt to log into this site on my iMac, it works just fine.
When I use the 1Password.app and attempt to log into this site on my MacBook Pro, I see the Log in form filled out, followed by the password blank reverting to blank and the banner: Couldn't log you in as "my username".
Can anyone offer any insight or guidance on why this may be so???
Better still, a fix for how to get it working on the MacBook?
