Hi CSE -
I'm not sure about dragging a headless dialog.
However, last week Friday I just completed a code demo of VWG's drag/drop functionality. I've successfully been able to implement drag & move with a Panel or UserControl.
So, instead of using a headless Form itself. You could mimic this functionality by simply having a User Control or Headered Panel that contains your dialog contents... so you could drag the UserControl or Headered Panel around the screen. Make sense?
