Error with Zonal statistics

Hi

 

I am using the spatial analyst zonal statistics tool to get the standard deviation of elevation.  For zones, I have a coarser raster with each cell uniquely numbered.

 

The tool runs without error, but the results for standard deviation (std) have zero in all zones.

 

Running the same analysis for mean or maximum gives the correct values.

 

And, running the same analysis after converting the zonal grid to polygons gives correct values.

 

Is this a known bug?  Or perhaps I missed something important.

 

cheers

Dan
