am using usrp2+WBX ,am doing this simple experiment - 
from a signal source i gave 1.5GHz(-20dBm) to usrp2. 
in gnu radio companion i gave-UHD:USRP source->wx gui waterfallsink 

 The Waterfall plot shows only a blue window without any signal and no control buttons. 
when i gave a wx gui fft sink i can see my input signal in fft spectrum 
what could have possibly gone wrong with waterfall sink     
(am using gnu radio companion 3.6.2,ubuntu 10.04)         

any help is appreciated
