I am running 1Password 3.9 as well as 1Password for Windows on a separate PC. They are synced over dropbox. When I add new logins on the windows pc, they do not show up in the Mac version unless I quit the app and restart it. Same thing if I add a new login on the Mac from the browser extension. Will not show up unless the app is restarted. No problems on the Windows version of the app in this capacity.
