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
