Hi Jason, thank you for your input.
I have tried to set an override Coordinate System but it seams like 
Maestro is ignoring the override.
By default the source coordinate system is (BYN75) which is the name of my 
tab file, I find that a littel strange.



In the override I set the target to (ESPG 25832) and then I validate my 
map, now I get an error that Maestro could not
get the spatial information from the datasource.

If I then change the source coordinate system of the override to the Wkt 
PROJCS["unnamed",GEOGCS["unnamed",DATUM["Euref_98",SPHEROID["GRS 
80",6378137,298.257222101],TOWGS84[0,0,0,-0,-0,-0,0]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433]],PROJE
 

CTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",9],PARAMETER["scale_fact
 

or",0.9996],PARAMETER["false_easting",500000],PARAMETER["false_northing",0],UNIT["Meter",1.0]]
 


Like this


Then I get the conversion warning I had from the start hmmmm

I have noticed another thing when I switch between Simple and extended 
view It loads the default coordinatsystem

Well Known is a bit of a misnomer for this stuff.  Most tools (MapInfo, 
ESRI, etc) have their own subtly different flavours.

You should be able to set an override Coordinate System on your data 
source to avoid this, but I haven't tried it myself to see if Maestro 
reads the override.

Thank you Jackie, 
You are absolutely correct. 
When i check the coordinate systems in Maestro the WKT code says for the 

Datasource (MapInfo .tab file) : 
PROJCS["unnamed",GEOGCS["unnamed",DATUM["Euref_98",SPHEROID["GRS 
80",6378137,298.257222101],TOWGS84[0,0,0,-0,-0,-0,0]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433]],PROJE
 

CTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",9],PARAMETER["scale_fact
 

or",0.9996],PARAMETER["false_easting",500000],PARAMETER["false_northing",0],UNIT["Meter",1.0]]
 


and for the Map coordinatsystem it is 
PROJCS["ETRS89.UTM-32N",GEOGCS["LL-ETRF89",DATUM["ETRF89",SPHEROID["GRS1980",6378137.000,298.25722210],TOWGS84[0.0000,0.0000,0.0000,0.000000,0.000000,0.000000,0.00000000]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["false_easting",500000.000],PARAMETER["false_northing",0.000],PARAMETER["central_meridian",9.00000000000000],PARAMETER["scale_factor",0.9996],PARAMETER["latitude_of_origin",0.000],UNIT["Meter",1.00000000000000]]


I just don't understand that when I set the Coordinatsystem (ESPG code 
25832) in MapInfo it gives something different i Maestro ?
