Scope with cygwin

Dear all,

I have not been able to have the scope work with my USRP and my TV front
end.

When I launch the script, the program seems to be freeze, but I can stop
it with Ctrl+C. And the FFT works fine.

I have a USRP board Rev4.5 and the TV Rx v3 front end. I used a decim
rate of 8, a central frequency of 474MHz and I work with Cygwin.

Has anyone already had this problem? Or any idea to solve it ?

Thanks for your answers.
