Need to click to get a key listener

Hi. I need to click in some part of the explorer window to make the movie "listen" my keyboard, and i strongly need to get rid of this click, otherwise it doesn't listen the key and stays freeze.

This looks like the old "click to activate", in fact it works exactly like that, but i'd tried with opera, chrome, firefox a even IE and i can't solve this. Also i've tried some old post that use and noClickToActivate.js, but it doesn't work either.

There is some configuration or file someone use and actually works?

Thanks in advance!
