At our current project, we have an application which is deployed using No Touch Deployment. Because of some SEHException we got a few months back, we started our application in a separate thread using a launcher class which contains the Main() method for the application. Recently we added functionality to display HTML pages our application generates, so we added the ActiveX webbrowser (in AxSHDocVw.dll).
