ABR10 dont remember e-mail password

Hi, I have a problem in two different clients using ABR10.

The problem is that I try to create an e-mail notification, I configure the settings and I can send an email test, this works well. But then I save settings and close the window and when enter again in the notifications settings I only see 2 black points in the email password field (the password in this 2 clients have 6 and 8 caracters, not 2), so when I try to send other e-mail test this fail and ask me the password again.

Resuming, ABR10 dont remember the email password for email notifications.

What can I do?

Thanks.
