Hi Pauline,
Thanks for investigating. Then I will be hopeful that the problem is fixed when
TDS WMS catches up with the latest ncWMS coordinate system code. FYI: I was
getting the blank images when loading the WMS GetCapabilities URL from our TDS
into Gaia 3 or Quantum GIS Open Source GIS packages:

Cheers,
John
