I just downloaded the 2015 version and I'm having a terrible time getting lines to snap to the right place. For instance, if I start a line and try to snap it to the midpoint of another line, it won't end up on the midpoint. Even though the point is highlighted with the yellow box and the box saying "Midpoint" pops up. If I zoom in I can be as much as .030" off.

Is anyone else having this problem?
