title: Multiple JComboBoxes with ActionListener
body: <p><strong>This code was taken from my original code and modified for testing purposes.</strong></p>
  
  <p><em>Question: Why is it that after clicking on a JComboBox, I cannot click on any other JComboBoxes?</em></p>
  
  <p><em>Purpose: After clicking on the JComboBox, the selection gets copied down to the JTextField.</em></p>
  
  <p><strong>I have read many other posts on StackOverflow and made those changes accordingly, yet they have not solved the problem.</strong></p>
