If you pinch in on the touchpad or the screen on a laptop or tablet, it doesn't zoom out to less than 50% and you have to click on the zoom bar instead. This appears to be a recent development. I have restarted my computer and it has stayed the same.

I'm wondering if other users can zoom out past 50% or if this is just an issue for me.

I'm baffled by why they might choose to make this a feature as you can't even see the full page at 50%, much less multiple pages in the multiple page view, and goes against the ethic of simplicity that Microsoft is always trying to go for.
