After clicking the Send button, Im presented with a login screen. What happened and was my email sent?
If you see the login screen, it means your session timed out. However, by loging in again your session will be resumed. This occurs because you took longer to compose your message than the predefined time-out period allows. Your email will be sent once you login with the screen presented. You can change the amount of time MyRealBox waits before timing-out your session, the time-out period is changed in Preferences / Options.
