title: Click on Captcha via Selenium always raised picture verification
body: <p>So i try to send <code>SMS</code> using <a href="https://globfone.com/send-text" rel="nofollow noreferrer">this</a> site via <code>Selenium</code>.</p>
  
  <p>After choose my country and my phone number i have this <code>Captcha</code>:</p>
  
  <p><a href="https://i.stack.imgur.com/TY33h.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TY33h.png" alt="enter image description here"></a></p>
  
  <p>So with <code>Selenium</code> i succeed to click on this <code>Checkbox</code> but allways got this <code>image verification</code>:</p>
  
  <p><a href="https://i.stack.imgur.com/SW2cg.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SW2cg.png" alt="enter image description here"></a></p>
  
  <p>i try to put several sleeps before this <code>Checkbox</code> click but this <code>image verification</code> is still exist.
  This behavior is not hapenning via manual scenarion so my question is why this is happening ?</p>
  
  <p>This is how i am find my elements and click on <code>Captcha</code> Checkbox:</p>
  
  <pre><code>IWebElement frame = driver.FindElements(By.XPath("//iframe[contains(@src, 'recaptcha')]"))[0];
  driver.SwitchTo().Frame(frame);
  
  IWebElement checkbox = Driver.Browser.FindElement(By.CssSelector("div.recaptcha-checkbox-checkmark"));
  checkbox.click();
  </code></pre>
