The scope freezes (in all modes) and it needs to be killed to get the
control back.
Has anyone experienced the same?
A GNU Radio flowgraph can generate samples much faster than wxPython can
display them. In fft_sink, fft_rate is the number of frames fft_sink
attempts to draw per second. Try adjusting it down. There is a similar
parameter frame_decim in scope_sink, again adjust this down until the
display updates and the program works.
Also, if the flowgraph data rate
is not limited by some hardware device (like audio or the USRP), you
need to put a gr.throttle block in the flow graph to limit it.
