      • I've got a WebBrowser control in my current program that, every minute and a half, loads a web page and parses some string information out of it.

      • Can someone refer me to a thread that addresses this issue I've seen one before, but I can't find it! I have some radiobutton_click events firing after the form_load event occurs. I need to make sure that I'm only responding to the radiobutton_click events after the form has completely loaded, but I'm not sure how to do so. Thanks, Heather
