Change default action of middle mouse button in Acrobat Pro

Like most modern mouses (I guess,) I have 3 buttons on my mouse -- the traditional right and left buttons, plus a center button, that doubles as a scroll wheel. The default action of my center mouse button in my Acrobat Pro is that it results in a small window popping up with an image of one of the pages in the PDF. (This only happens if the PDF has more than 1 page; but, I almost always work with PDFs with multiple pages.) My center button is very sensitive, so I routinely hit it accidentally, resulting in the window popping up, which stops the pages from scrolling.

I would LOVE to disable this feature for all PDFs. Or, at least,  change the default setting  to something more benign, like maybe the hand tool? Is there any way to do this???
