Slide In sliding out immediately when I stop scrolling

A client of mine wanted to use expensive software to integrate with his website in order to (among other things) use a Slide In. I installed Slide In for him, to save him some money, but it's currently acting kinda useless.

It displays as it should (would love to have the option to use the corners for display btw), but once I stop scrolling or try to come near it with the mouse: it disappears.

I'm using a custom made Genesis child theme.
