Thanks for testing.

The mapping error can be easily fixed.

if sys.version_info.major > 2:
    basestring = str
    map = lambda a, b: [a(_b) for _b in b]

I'll update the script accordingly.

For the Script-Button: Don't know how to start searching why it will not work.

I think a simple wxPython Dialog is the best solution for the moment. I'll make one today.
