Lou,
The first thing I notice is that you are specifying the elevation file over
and over, which is unnecessary. Secondly, I have had problems with GDAL
opening multiple ECW files at once - it can run out of memory and freeze
up.  If they are small enough to convert to TIFs, try that and see what
happens. -gw
