Slide in plugin wont stay open

I am having a problem with the slide in plugin. It is not staying open long enough to interact with what I placed in it, in this case a form. on my end, it will slide into the window on page load and when you scroll, but if you stop moving, it will slide out of the window. also, it will even hide when you mouse over it. What can I do tho fix this weird behavior? you can see what I mean here:
