Thanks Markus,

The lines are from CoClassBaseClass:
...
# This CoClass is known by the name 'EDREUTLX.EDREUtlXCtrl.1'
class EDREUtlX(CoClassBaseClass): # A CoClass
...
That would be a helpful bit for the docs! 

So, the util class Dispatches, but all calls (properties and functions) give 'Catastrophic failure'
Is this really some sort of types problem with this OCX?
"pywintypes.com_error: (-2147418113, 'Catastrophic failure', None, None)"

Thanks for the help,
Ray
