I have an ASP.NET project I use for testing different things, ideas, etc. One form in the project contains various controls and several buttons used to test different things. I added a button to the form and set up the Click event in the code-behind and ran the form. I noted that when the form is first run, clicking the new button fires a post back to the server as expected. But when the form is run, if a different button is clicked forcing a post back to the server, then the new button is clicked, nothing happens, as if the button is not even wired up. What would cause this kind of behavior?

Thanks,
Bill
