Digital BW, The Print

I upgraded to Nik Sharpener Pro 2.0 and there do seem to be some marked 
improvements.  However, one of the reasons I upgraded was to get 16 bit 
capability. At this point, 2.0 only works with 16 bit RGB files; if you 
have a 16 bit grayscale file the option is still grayed out in the 
filter menu.  Tech support said that they are working on the problem.

Additionally, it is not clear to me that the new "smart sharpen" in CS2 
works as well with grayscale files as it does with RGB.  I have been 
very pleased with the results when I sharpen a RGB file, but 
disappointed when I try smart sharpen on grayscale.   Am I imagining 
things or has anyone else had the same experience.\?
