There is nothing firing anywhere else and the Editboxes do not have any ControlSource property set. Look at one of the above threads from Robert about controls in containers. I also just tested this and it is true. If I add 200 Editboxes to the Form. I don't get much performance degredation at all. So I am rethinking my method of displaying these. I will next test them inside of a Page on a PageFrame to see if they still work OK.
