[mapguide-users] can anyone solved this buffer problem

[Kenneth Skovhede, GEOGRAF A/S]

I'm not sure that provider is case insensitive.
Try adding the file again, but with the name "PROPERTIES.shp".

Also, try creating a folder, and place the files in the folder.
Then try to use the "External files" and point to the folder.
Also try pointing directly to the file.

When the "Test connection" is successfull, try clicking the
rightmost button in the "coordinate system override" field, and
it will show you what the provider returns as the coordinate system.

Alternatively, try using the OGR provider instead of the SHP provider.
