title: Event Handlers not Firing for Winform Launched from Excel Addin Ribbon
body: <p>I have an Excel Addin Ribbon that adds buttons to the Excel context menu. The context menu instantiates a form class for performing certain actions. These actions work fine, except for one button, which actually shows the form. The form launches, but the event handlers on the form do not call the their respective methods. So the buttons and other elements on the form will not work.</p>
