Issue with interaction to py3270

[ginkson]

i keep getting an erro when running the tool:

Traceback (most recent call last):
File "./cicspwn.py", line 2607, in
main(results)
File "./cicspwn.py", line 2355, in main
if not check_valid_applid(results.applid, do_authent,custom_cics=results.custom_cics):
File "./cicspwn.py", line 347, in check_valid_applid
do_authenticate(results.userid, results.password, pos_pass)
File "./cicspwn.py", line 298, in do_authenticate
em.move_to(pos_pass,pwd_y_pos)
File "/usr/local/lib/python2.7/dist-packages/py3270-0.3.4-py2.7.egg/py3270/init.py", line 383, in move_to
xpos -= 1
TypeError: unsupported operand type(s) for -=: 'NoneType' and 'int'

As i see it, it's more of a py3270 issue but wanted to see if anyone had any tips.
