I've been writing a DHTML control and have noticed it flickers a lot when resized with 'Show window contents while moving/resizing' on. This happens even with the unmodified wizard-generated DHTML control (using vs.net, add atl control, dhtml control). The control works by using CAxWindow as an activex container window and creating a control (IWebBrowser2) inside it. For an example, create the dhtml control with the wizard, compile, then drop the control onto a form in vb/c# and make it fill the form. Then compile that and resize it. Although I've read up a bunch about flicker, I'm not quite sure how I'm supposed to extend or modify CAxWindow to remove this flickering. Any ideas?
