title: DataGridViewComboBoxCell back color changes
body: <p>DataGridViewComboBoxCell displays normal when application launched</p>

  <p>After selecting the value, background changes to black (see below) on the current row and subsequent rows. I have used default DataGridView and no font manipulation</p>

  <p>I have tried changing color in CellFormatting and CellMouseClick events. But still the same behavior. Any ideas?</p>
