Stay up only works for On right mouse down when clicking on thumbnails or file icons, but not for On left/middle mouse down

"Stay-up" is only a sub-setting for right mouse button. So I believe from day one incorporation, it was only intended for the right mouse button. It would have to be a wish to be anything beyond that.

Yeah, now I see. You're right.
