[mapguide-users] Connecting to WMS

[Kenneth Skovhede, GEOGRAF A/S]

If the problem is as Tom describes, it is likely because Studio uses the 
CSMap coordinate system,
and MGOS uses Proj.4.

If you setup an override using Studio, it is invalid for some coordinate 
systems, because they are named
slightly different in Proj.4.

Try using Maestro to setup the override, as it uses the server 
coordinate system, regardless of brand what it is.
