Bonnie,

I had a feeling that the question would be more appropriate for .NET forum , but since Foxpro behaviour was involved decided to send to this category.
Yes , thanks, delegate was set up twice and after commenting it in a parent Form Foxpro behaviour was achieved. What I didn't like though is that I had to comment in Designer generated code. Surely more control how inheritance works , but it is not purely visual.

I think I need to see more of your code (I'm thinking possibly you've set up a delegate to the twButton1_Click event handler in both Form1 and Form2 and you wouldn't need to do that in this case).
