F5 - New sell order throws an error

[prologic]

The F5 key for New sell order throws an exception:

014-01-05 16:22:54,086:DEBUG:__main__.PrintHook:Exception in thread Thread-96:
Traceback (most recent call last):
  File "/usr/lib64/python2.7/threading.py", line 810, in __bootstrap_inner

    self.__target(*self.__args, **self.__kwargs)
  File "./goxtool.py", line 1281, in cursor_placement_thread
    curses.curs_set(2)
error: curs_set() returned ERR

The dialog does open however; but as the F4 (New buy oder) doesn't work I haven't been able to test this. See: Issue #51
