Whenever I subdivide or extrude a Bezier curve, I always get an odd pinching effect: 1, 2. Either at the point where the subdivided handle is, as seen here: 3. Or at the handle that I extruded from, as seen here: 4. This is very annoying, as it means that I can't fine-tune a Bezier curve by adding more points to it. If I try, this ugly artifact crops up, ruining the appearance of the curve's geometry.

Why does this happen, and is there some way to fix or prevent it?
