I have two controls on a form that reference the same activeX control. After the Application.Run(myForm), one of the controls works, the other does not. The code in the constructor of the form is exactly the same for both controls. Can you have two instances of an external ActiveX control on the same form?

Upon further review, it initializes the first instance and gives an error about windowless controls on the second.
"System.Reflection.TargetInvocationException: Unable to get the window handle for the '<ActiveX name>' control. Windowless ActiveX controls are not supported. ---> System.NullReferenceException: Object reference not set to
an instance of an object."
This control is not a Windowless control... Any ideas, or did I find a bug?
