Have noticed this for about 6 months now that it's impossible to change passwords. I go to login with the saved one (from last change) it doesn't work, so have to use the emergency login, it asks me to change the password, I do, but it never will login with the new one again. There's something in the web-code adding, or changing the characters entered-in so that what is entered is NOT what the system records. Might be worth looking at.
