Sometimes, when I zoom in on an object in the 3D view - perspective, there comes a moment when I cannot get closer no matter what. Then also, orbiting and panning become extremely slow, like in cold mollasses. By pure stupid luck, at a given moment, a bit desperate, I used Numpad dot, and it did not only bring the selected object in full view but also unstuck the zoom, allowing me to zoom in or out speedily and at will.
So, I guess that I don’t have a zoom problem anymore, except for the fact that I don’t understand why I had one at first. It really bothers me to rely on a “workaround” that may very well not be one. Anyone with an explanation of the causes ?
