If I try and view my passwords by going into dropbox.com and opening 1password.html, I run into an issue. (This is something I have to do often on remote computers or on any Linux box.) In Chrome or Firefox, any passwords that have the "<" character in them are truncated at that character. If I had to guess I would say that the web interface doesn't literal out special HTML characters.
I know I could just set the password generator to not use special characters. However, this seems like a thing Agile WS could fix this very easily.
