login/ register /password recovery problem

doing test of register/login/password recovery

1) after register, login automatically ----good, log out then login again, doesn't work, have to restart application, then ok

2) deleted customer from admin side, then use same email register again -- error "The specified email already exists".checked database, the email address exists, but the customer not in admin>customer list

you have to manually delete the user record from database otherwise when you delete from the admin panel system checks a deleted flag and the same email adress already persists in the system

i didn2t understand the first one what do you mean? logout and login works you don't need to restart anything
