Zooming in manually doesn't really zoom in low levels

[KayleMaster]

So the problem is when you zoom in without clicking on a system, scrolling the map becomes unbearingly slow (scale modificator or something?) and the systems as well as the ring around a hovered star. I can never zoom to the level which you can achieve by clicking on a star.

Example:

Happens if you tilt the view to look sideways and the til it back to normal.

Weirdly enough, when this state is reached, the left mouse button rotates the camera's view and not the galaxy. It seems the focal position is almost near the camera. Any idea?
