    That looks like a bug that we should be able to fix easily, either by changing the StyleUtils.IsHottracking method to return false if the specified control's IsHandleCreated property returns false, or by bypassing that logic altogether when the control is in the process of being disposed. You might want to report this as a bug.

    Note that in the meantime, you might be able to work around this by assigning null to UltraComboEditor.DataSource in response to the FormClosing event, or whatever it is that triggers disposal.
