Paul, you rock!!!!

Changing the decimation factor (-n) to a bigger value (the default value is
1) works like a charm and solves all my GUI freeze issues, even within
VMware. I started with "-n 100" (as you suggested) for usrp_oscope.py, but
it is too much and the refresh rate is very slow. Then I tried, 10, 5, and
in my case, it even works great with "-n 2".

Thanks a lot!!
