Can't constrain a path while dragging with the direct select tool?

[chadh64331598]

Seems like in the past month or so, if I want to drag a point on a line and have it be constrained to 0° or 90°, the point will not move while holding the shift key. If I let go of the shift key, it will go where ever I want but not constrained to straight up down or across. What is going on? I've searched but haven't found anything similar.

Are smart guides turned on? Try and turn them off.

Not sure I know how to globally turn them off. I see options in the Preferences, but not "on" or "off". I turned off alignment guide and it had the same problem.

You can solve that by removing snaps commands from View> Snap to grid or other snaps that active.
