    Detail functions of Sharpening and Noise Reduction stopped working

    Raw User

      Recently upgraded to CS4 from CS2, and installed ACR 5.3.  Everything worked fine until suddendly the Detail tab items (Sharpening and Noise Reduction) stopped working.  Sliding the sliders did nothing to the image.  Also, holding down the Alt key (I use Windows XP Prof.) and sliding the Sharpening sliders did not show greyscale functions.  I have updated to ACR 5.4 but it makes no difference.  A couple of times the Sharpening and Noise sliders have worked again but then they stop.  Other parts of ACR appear to be working fine.  Any ideas on resolving this weird situation?
