How to disable drag handles snapping to intervals?

Whenever I drag a handle for a 3D feature (extrude, revolve, etc.) it snaps to some fixed increments, rather than allowing me to smoothly and continuously drag it. Surely there is an option to disable this snapping, right? The only workaround I've found is to set the interval values to very small numbers, but surely there is an "OFF" switch for this snapping behavior, right?
