Hi,
        When I run usrp2_fft.grc, it just hangs on execution, nothing gets 
displayed and the FFT plot doesn't get updated.

I've set the frequency to 104.1M, decimation value to 16.

The FFT Plot gui is completely un-responsive. I'm using Ubuntu-11.04 with 
gnuradio-3.4.0.

Try doing two things:

Turn on averaging
Turn down the FFT frame display rate from the default 30, to something like 5

What type of system are you running on? What CPU, what speed? Multi-core or single-core?
