I am having this problem all the time. The defaults for the fft display are to try to display 15 fft's a second which is too much for anything but the fastest processors.
In the usrp_wfm_rcv example several fft's are displaying at the same time which worsens the problems. I allways add the following parameter to all ftt's. fft_rate=5 What this does is to tell the fft gui to try to display 5 fft's a second in stead of 15. For me this solves most gui_freeze problems. If you still have the problem then go even lower as 5 or disable the fft's. (change the if 1: to if 0: in front of the code which opens the fft display) Maybe it is a good idea to add fft_rate as a commandline parameter to all examples. And maybe lower the defaults in the fft gui. Another problem which I have witth the examples that it always barks at the import powermate line (I don't have a powermate) If I coment the line out the code runs fine. Anybody got a solution for this?

I sometimes experience the same behavior, but it usually goes away after a couple of seconds. It might be an issue with ram if you have a lot of programs concurrently open. 256MB isn't much. Can you see how much memory is in usage? You can use top and free to get this information.
