[mapguide-users] Connecting to WMS

[Stefan Dalakov]

Kenneth, I missed somehow the problem, described by Tom, but I have to 
say that Gunter was absolutely right and helpful. I moved the project to 
MGOS 1.2 (luckily I have both versions installed) and now it works as 
expected.
Thank you !

Stefan
