title: DataGridViewComboBoxColumn - Have to click cell twice to display combo box
body: <p>I am using a <code>DataGridView</code>, created using the designer with a few columns including a <code>DataGridViewComboBoxColumn</code> column.</p>
  
  <p>It is slightly irritating that I have to click on each cell twice or even three times to display the drop-list:</p>
  
  <ol>
  <li>If I click over the text part, it takes <em>3</em> clicks!</li>
  </ol>

  </ol>

  <p>I assume it's due to the cell using the first click to get focus, but is there a way to address the issue so clicking on a cell displays the combobox right away? I note that using <code>DataGridViewCheckBoxColumn</code> the same issue does <em>not</em> happen... clicking on a checkbox immediately toggles it regardless if that cell had focus.</p>
