Jim,

Thanks for your quick reply. As I had mentioned the control is a third party product. What I don't understand is why the control is fine on many machines, but I'm having a problem with this one machine.

The control(s) are dynamically added at run time onto an existing visual form but I believe by using addobject(), don't know if that's the same as createobject(). Again, I would ask, why is it not a problem with certain machines.
