Disable a right click (press and hold) in WPF application.

Question

I am working on the touch screen application which is running on Windows XP Standard. With current hardware to invoke a right click user has to click and hold for couple of seconds, but this might interfere with other actions like holding a repeat button in the scrollviewer, so I have decide to disable a right click.

I would ideally wan't to disable a right click on the application level, but if it is not possible, disable right click on windows level would also work for me.
