title: Cannot focus on element - Selenium, Chrome, Python
body: <p>I am trying to go to the drought monitor website and tell it to select to show county data. I am able to get my code to navigate to the website, and it clicks the dropdown, but I cannot get it to type in "county". My code gets to the last line and then give the error: "Cannot focus element".</p>
  
  <p>Any help would be greatly appreciated as I'm very new to Selenium.</p>
  
  <pre><code>from selenium import webdriver
  from selenium.webdriver.support.ui import Select
  from selenium.webdriver.common.keys import Keys
  
  browser = webdriver.Chrome()
  browser.get('http://droughtmonitor.unl.edu/Data/DataDownload/ComprehensiveStatistics.aspx')
  
  browser.maximize_window()
  dropdown = browser.find_element_by_xpath("""//*
  [@id="dnn_ctr1009_USDMservice_CompStats_2017_aoiType_chosen"]""")
  dropdown.click()
  dropdown.send_keys('county')
  dropdown.submit()
  print("I'm done")
  </code></pre>
