Thanks merceg, I'm trying to avoid the training material from looking like an application, with the minimise and close icons,and the small border round the outside.For the time being I have used the borderless feature and have set the entire project to run at 1024 x 768 with a black background, thus any 'pages' which are smaller have a black border to them.It would be nice to dynamically re-size the projects main window without a frame.Regards, Kurt
