It looks like I didn't catch this message when it was posted. The TopBar slides down after the page has been scrolled a bit. The way the person chooses to scroll doesn't affect how it functions; it is fixed to the top of the screen and won't push your content up or down, because it is an overlay. You can scroll up and down and still see all of the content on the page whether the TopBar is visible or in a dormant state.
I'm not sure how it is 'breaking' your site. Is having it active interfering with certain features and functionality? If so, we'd love to look into the issue and iron out any bugs. If the TopBar isn't conflicting with another plugin/script or your theme, it does work as intended, sliding out from the top once the reader has scrolled and disappearing when near the top of the page.
