Recently upgrade to Lightroom 4 and adjustment brush does nothing.

I click on the brush and reset all the sliders with the exception of exposure, for example.  I have set to brush and start brushing on the target area.  Nothing happens and does not show the red mask overlay on brushed surface.  Use Mac 10.6.8.  I have also several catalogs upgrade - catalog Lightroom 3-2, -3 and -4.  I'd rather have a single.

Check the flow rate (how long the effect accumulates) and density (how high it can go).
