I have been googled for couple of hours but couldn't find a solution

I m doing a touch screen interface, to browser a page I used a webbrowser control, and in order to get ride of the ugly scrollbar, i m trying to use mousedown and mousemove event on the webbrowser to move the page around, it worked but when i m doing it, it select and highlight the content on the web too, how can i stop that?

do I need to create a extended webbrowser control by Inherits the orginal one?
if so, which event should i capture and override the handler?

how can i add more event and event handler on this example to achive that?
