Cannot set Fullscreen on Piston Window - Windows 10 Surface Pro 4

[gregelenbaas]

Hi everyone,

Been playing with Piston and it's pretty great. However, my program crashes before starting when I set fullscreen to true. I'm running a Windows 10 Surface 4 Laptop. Sometimes I use a second monitor but it doesn't work with it connected or not connected. Below is the program code:

`
extern crate piston_window;

use piston_window::*;

fn main() {

let mut window: PistonWindow = WindowSettings::new(
        "piston: draw_state",
        [600, 600]
    )
    .fullscreen(true)
    .exit_on_esc(true)
    .build()
    .unwrap();

}
`

Here is the stack trace:

Thank you for the help
