[Qgis-user] No GetFeatureInfo request sent in QGIS Desktop on WMS layer

[Andreas Neumann]

Hi Barend,

Thanks. It's been a while since I last worked with UMN map server.

I must have been "blind" not to see the queryable="0" in the 
Capabilities response.

Your suggestions helped. All fine now!

Thanks a lot,

ANdreas
