Manual adjustments in Curve Editor

Hello!
As mentioned here:
The Curve Editor (http://www.imagineersystems.com/support/Documentation/the-curve-editor)
“You may move the keyframes manually by dragging them with the mouse, or you may type in a ?Nudge? value at the top right of the Curve Editor.”
The problem is when I drag the points of the curves manually the values are not updated. And if I press the Nudge button the point is reset to its previous location (the same if I save and reopen the project).
Using the Nudge button by itself is OK, but constantly changing the values is a bit tedious.
Am I doing something wong?
I am using Moca Pro 2.6.1 build 4014
