Keyframe graph editor - can't adjust scaling with mouse

I mainly animate anchor point and it happens every time I've tried it there, but I did try it on other properties as well, like position, scale, rotation, opacity, etc, and they all appear to be encountering the same problem. 

Yes I can manually type in a scale and that's what I've needed to do. Slower or faster mouse drags don't help. I've also tried moving the mouse up/down rather than left/right, same problem. It's like the values start going in the direction I want, but they keep being pulled back towards the original value.

Hi @morphinapg, 

Thanks for reporting a problem. Is this happenning with all your keyframes, or only some? Are you able to select the 200 and input a number with your keyboard? Do you see any difference in a slow drag vs a fast drag? 

Sorry for the frustration, 

Dani

Try resetting the preferences:

If that doesn't work, try creating a new project and import the old one into it.

That doesn't solve it for me. Already didn't have caps lock on, and already had num lock on.

I had that happen once.  Turning off caps lock and turning on num lock fixed it.
