In Lightroom 4 when I press on and hold down the ALT key, I can't move the slider black and white

In Lightroom 4 when I hold down the ALT key, I can't move to the black or white and it does not show the clipping. Essentially, I am now the ALT key and the sliders will not move. I'm doing something wrong? Thank you.

There was a problem with the integration of my mouse. All fixed.
