If you set a property on a Windows Forms control which forces the creation of the control (e.g. the SelectedIndex property on the ComboBox class), the control (and perhaps the rest of the form) will not render with visual styles enabled.
The resolution is to place the code that sets these properties in an event handler for the Load event on the form/control.
