When I try to move around my scene to get a better look at things, I'm finding some aspects weird, but only sometimes. For example, when I mouse wheel to send my view inwards, it only goes so far, and then slows WAY down, and won't go any further. Secondly, when I mouse wheel down to rotate my view, it feels like it's rotating around some other thing, rather than just rotating. Thirdly, when I'm zoomed in, mouse wheel down and drag to move my view goes extremely slowly. Zooming back out lets it go normal speed again.
This is making my work extremely painful to do. Anyone have any ideas why this is happening, or how to fix it? Thanks!
