I can reproduce something similar I think on Ubuntu 8.04 using recent svn sources with the included grc to make an audio signal source and scope sink, not using any usrp etc.
The scope gui displays the waveform but the mouse cannot get focus on any buttons. Then I installed the latest stable release of gnuradio 3.1.3 and the separate grc 0.7, and everything works correctly as expected.
