1Password 4 continually starts with "Awesome! Let's get Started", and forgets Dropbox sync setting

Hello,

1Password 4 started misbehaving recently (since 4.3 I believe), and each time it starts up, it runs the "Awesome! Let's get started" routine. 1Password also forgets that Dropbox sync is active.

The first time I found Dropbox sync in-active (and well-knowing 1Password's buggy merge when you re-activate Dropbox Sync, and 1Password possibly overwrites passwords recently-updated on other devices back to their former state, thereby losing the new passwords), I followed advice from "Starting over [ with 1Password 4 ]" at http://learn2.agilebits.com/1Password4/Mac/en/KB/start-over.html .

rm -fr ~/"Library/Application Scripts"/*agilebits*
rm -fr ~/"Library/Containers"/*agilebits*
rm -fr ~/"Library/Group Containers"/*agilebits*

After this reset, when I start 1Password again, the following are the steps:

• "Welcome to 1Password 4" -> "Awesome! Let's Get Started"
• "We found your data in Dropbox. Unlock it with your Master Password...."
• Security -> "Lock after computer is idle for 5 minutes."
• Rich Icons -> "Use Rich Icons"
• 1Password Mini -> "Always keep 1Password mini running"
• examining Preferences shows Dropbox Sync active, and all is good

After a log-out and log in, though, 1Password starts up again with the "Awesome! Let's get started" routine, but the steps are slightly different:

• "Welcome to 1Password 4" -> "Awesome! Let's Get Started"
• no mention of Dropbox; just an unlock screen
• again "Security"
• again "Rich Icons"
• again "1Password Mini"
• examining Preferences shows no Dropbox Sync active, and I have to follow the reset steps above again

I've run the 1Password troubleshooting tool (http://learn2.agilebits.com/1Password4/Mac/en/KB/troubleshooting-utility.html) for permissions and extended attributes to no avail.

I'm hopeful you can offer advice.

Regards.
