Problem getting the LBUTTONDOWN from a windowless application!

Hi, I am having problem getting the LBUTTONDOWN message from the DesktopExplorerWindow.

The problem is that I cannot use any window in my application, because I wan´t to seamlessly fade from the desktop bitmap to an application bitmap using the directdraw blit for the primary surface( that is the DesktopWindow.... ).

If I create the window, during the launch of the window you can see the borders of the window coming from nowhere and then expanding to the real size of the window.

That is precisly what I don´t want to see!

I have tried to create the window without any border, specifying only the WS_VISIBLE style, but with no luck.

So, how can I get the LBUTTONDOWN message from the DesktopWindow not using any window?

Thanks, for taking your time, Dani
