I seen an older post with this in it:

Code:
  
$ButtonCancel = $FormQuestion.Button('Cancel', $ButtonOK.Right + 10, $TextBoxAnswer.Bottom + 5, 40, 16)	
$ButtonCancel.Cancel = 1	
$ButtonCancel.OnClick = 'GOSUB ButtonCancel_Click'


But wasn't sure how/if it worked. My kixfroms.dll is showing version 2.2.0.37. Thanks!
