I thuink I know what happened to cause windows logon each time I view a password. Note: I never had to enter a password in the past because I never had a windows logon!
I recently created a Skype account which somehow required me to create a windows logon acct. After that, the entire browsing of passwords in Opera changed, for the worse. This must have caused it. They also made me put money into an acct, which I now cannot get back. Bastards.
