When installing Zabbix 1.4.2 web frontend, step 4 "stars" out the database password and makes it invisible for people looking over your shoulder. However, page 5 (after the connection check), shows it in plain text.

I think this behavior is not something you would want.
Either show the password in screen 4 so the user knows he has to be cautious, or (better) remove the password field from step 5.
