So if i have to change this values I have to type the numeric values.

Its kind of weird because I haven't read someone having this trouble, in version 11 worked fine.

Currently using Resolve12Beta2 on Yosemite 10.10.4

Is that happening for all controls?

The 2 controls you point out do work here with click and drag on Mac.

What type of Mac are you using, and what type of mouse?

Yeh its happening for all controls of this kind.

I'm on a Mac pro and using a wacom intuos surface mouse.

* I just tried the pen instead of the mouse and it worked fine, also connected another wireless mouse and it worked as well. Guess its just the wacom mouse, though the mouse works fine in any other program.

Cheers.
