First, I'd like to compliment you on a great product. I purchased both the Mac and Windows versions and love using them.
My 1Password is configured to not auto-lock (all three auto-lock checkboxes on the Security preferences tab are not checked).
I keep the 1Password database on an encrypted USB Flash Drive. This makes it easier to share between my Mac and PC. Recently I noticed that the USB "Safe Remove Hardware" doesn't work anymore. After investigating the problem I found that the Agile1pAgent.exe is holding on to the database files on the flash drive even if all internet browsers are closed. So now I have to "End task" the Agile1pAgent.exe, then "Safe Remove Hardware" to unmap the flash drive and finally remove the USB stick.
Would it be possible to alter the Agile1pAgent.exe behavior so that it doesn't lock the database when not in use?
