help(iopro) throws TextAdapter exception

[ijstokes]

I have IOPro 1.7.2 installed on my Mac, under Python 3.5 and Anaconda 4.2. When I execute help(iopro) I get a TextAdapter stack trace as follows:

/Users/ijstokes/anaconda/lib/python2.7/pydoc.pyc in docmodule(self, object, name, mod)

   1096             if (all is not None

Please advise how to move forward.
