Re: [Discuss-gnuradio] WX GUI FFT Sink error

[William Pretty Security]

Hello All;

Thanks for all the feedback (wow!) ...
Sounds like I'm hosed :(
I'll just tell the client not to use "Persistence" for the time being ...

Marcus: How is that ulcer of yours doing? Have you tried decaf ? <grin> 

Later;

Bill

I would like to be wrong, but as I recall, persistence was a non standard
