Method Client.Login.Login doesn't work well...

What steps will reproduce the problem?
1.Chunk of code (with Tibia Client 9.10 opened) :
  private void button1_Click(object sender, EventArgs e)
        {
            List<Client> cliente;
            cliente = Client.GetClients();

            Boolean logged = false;   

            foreach (Client c in cliente)
            {
                if (!c.LoggedIn)
                {
                    logged = c.Login.Login("user", "pass", "player");
                }
            }
        } 
If i run the program step over, the API can login inside client correctly. But 
if i run the program without breakpoints, the API cannot log inside the client.

What version of the product are you using? On what operating system?

Tibia Api for 9.10
Windows 7
