Pressing the cancel button in the register screen will return you to the login window. but when you press the register button, it will create your account but it wont take you back to the login screen as the cancelbutton does.

Now the cancelbutton and the function that makes you go back to the loginscreen are both in client side. So I know I'm doing something wrong on server side as in there it tells to use clientside function to close the registerwindow after the account has been created (both by clicking the register button).
