Aaron,

You wouldn't typically observe a view class.

In this case what your problem is that NSSlider doesn't change it's internal value in a key value observing compliant manner. You should observe the underlying value that the slider represents in your controller.

If you're using bindings it will 'just work' otherwise if you're using action messages in your controller be sure to send the proper KVO messages when you change the value - these are typically done in the accessors.

Keith
