Dude will not move

Camping website is slowly progressing. It´s still an early stage, but if anyone wants to take a look some of it is online here :http://www.printaporter.net/ai/main.html

Don´t mind the preloaders and the visible clips that sholud be invisible. Also ignore slopiness of the limits and the masking. I´m a slopy guy. I´ll clean it all up when i have the mechanics solved.

Notice how after loading the thing u can´t really controll the dude (he´s controlled with the cursor keys) untill u click the screen. And this is my question. I´d like to not have to click the screen to move the guy.

Ideas?
