Using a PageControl type notebook and wanting to resize the page contents as the program window is resized, it only works when a specfic page is open. All pages resize when the one page is open, but none resize when other pages are open. I think the page that triggers the event is the page that was open when the event handler was created. I want the form to resize no matter which page is open. Is it possible that editting the (sender: TObject)can affect the event trigger? Any clues on any of this?
