[ka-Map-users] tiles desappears

[Roberto Stecco]

hi all,
I have a problem with a raster image in ECW format.
when I try to load it in ka-map (cvs version 2006-03-30 - MS4W 1.4.0) 
and to create a legend with group (in map file), at first some tiles 
appear, but soon are replaced by empty tiles.
my map file is something like this....

if I uncomment GROUP "raster", nothing is loaded.
Any comment or suggestion?
