Hi All,
I have been trying to run the HF explorer example that was provide
with gnuradio with a basic RX board in the USRP, by I continually get
this error.

/usr/share/gnuradio/examples/hf_explorer$ ./hfx2.py -R B -c 3.697e6
>>> gr_fir_ccc: using SSE
Traceback (most recent call last):
  File "./hfx2.py", line 799, in <module>
    app = MyApp(0)

  File "./hfx2.py", line 794, in OnInit
    frame = MyFrame(None, -1, "HF Explorer 2")
  File "./hfx2.py", line 371, in __init__
    em.eventManager.Register(self.Mouse, wx.EVT_MOTION, self.fft.win)
  File "/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode/wx/lib/evtmgr.py",
line 103, in Register
    if not self.__haveMessageAdapter(listener, topic):
  File "/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode/wx/lib/evtmgr.py",
line 290, in __haveMessageAdapter
    return self.messageAdapterDict[topicPattern].has_key(eventHandler)
TypeError: unhashable type: 'fft_window'

No gui comes up and I have to kill the program with ctl-C.

I am guessing from what is says that there is something wrong with the gui.

I have not been able to find any info on google as yet (am still
looking though) if someone on this list has some more information that
would be great!

Thanks :-)
