Not working with CloudFlare's Rocket Loader

I’m running the latest version of the fixed widget plugin and have rocket loader enabled so all js are loaded asynchronously which shaves a whole second off my loading time but it breaks the fixed widget. If I go to another page after the initial page load then the fixed widget works. Any idea to fix this?

I am not minifying the .js using any plugins or CloudFlare.
