I use Password safe on several computers (home, work, phone). I store the database in Dropbox, and it works great. Except for one thing. Password safe always keeps the database open and locked, so the Dropbox application can't sync it. Is there some way to make Password safe automatically close the database when I minimize the application (or after X minutes), and then when I open it again, that it re-opens the database automatically (and require me to enter my password again)?
Try this: Under the Manage menu, click Options. On the Backups tab, make sure "Save database immediately after Edit or Add" is selected. This is how I have my Password Safe set up, and I keep my database in Dropbox as well and rarely have conflicts, even when the database is open on one device and I'm accessing it on another. Dropbox should sync the database automatically every time it saves; having it open and locked shouldn't interfere with syncing.
