This sounds a lot like cpu overconsumption. Look at the output of GRC,
does it tell you
>>> Warning: This flow graph may not have flow control: no audio or
usrp blocks found. Add a Misc->Throttle block to your flow graph to
avoid CPU congestion.
If not, do it anyway.

I run a flow graph under GRC with WX GUI widgets (sliders, FFT sink,
etc) on Linux. The graph works and I can receive signals, but the GUI
is not responsive (I can't move a slider, choose between radio
buttons), and it gets grayed out after a few seconds. The flow graph
continues to work and the graphical FFT sink continues to work: when
there is a signal, I can see it on the FFT sink and I can hear it in
the audio sink.
If I generate a python script from the graph and run it on the command
line I get exactly the same behavior.
Why is the GUI not responsive?
Thanks, Sivan Toledo
