Program Window Zoom Feature in Beta 25.1

Maybe there is a post already on this but I cannot find a clear answer. I am on a MacBook Pro, using a magic mouse. Every time my cursor goes to the program/preview window, if by mistake I touch the top of the mouse, it starts zooming. Not a fun feature.

I read that the Beta version 25.1 fixed that feature of gave us more control. I installed it in hope of having more control. Nothing changed. Is there something I should do? Is there an oprion I am missing?

Thank you for ll the help of this community.
