Form flickers on modal dialog close

Hi, I am C# beginner. I am facing some flickering problem. I am launching modal dialog while form load and I am also displaying form also same time. I mean on the form constructor I am calling form.show() and then launching modal dialog. After I close the modal dialog the form flickers (or blinks). How do I avoid this issue. I don't know this is place to post-message or not. If you provide a solution I will be really appreciate. Thanks, Parthipan
