I never use the peak hold button on this machine because I cannot click any buttons on the screen begin the program running, it is also dead as the same time. As I said before, I cannot do nothing only force quit :( I really want to know how to fix it. On my other laptop, I do not meet this problem. And the system difference between the two computers is that I install the grc part in the laptop which met the problem. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio Try setting the graphical-display rates to lower values.

If you *dont* use Peak Hold, does it work? There was a problem, deep in the bowels of OpenGL related to the Peak Hold function that seemed to cause this behaviour. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
