ps.map

[Jean Pierre Ratte]

Hello,
I'm a new grass user and my first problem is with ps.map.
I have two platforms: IBM RS6000 with grass4.1 update 4
                          and PC linux with grass4.1 update3 (binaries from 
moon.cecer...)

On the first platform: ps.map work fine but raster map are always in 
greyscale but  legend in color !
                                Is it the right use of ps.map, or made i a 
mistake somewhere?
On the second platform with the same database and same parameters: ps.map 
scratch wtih a "floating point error "
and warning about G_set window().

Any ideas to find solutions??
Thanks a lot.
