title: cursor does not change to I-bar on mouseover JTextField
body: <p>Initially the cursor changes to i-bar on mouseover, but after clicking a button (which basically calls setEnabled(false) and then setEnabled(true) on the JTextField) ,  the cursor doe not change to i-bar on mouseover JTextField.</p>
  
  <p>What could be the reason? Any help or hint in right direction is most welcome.</p>
  
  <p>The focus is also present in both cases.</p>
