[Discuss-gnuradio] WX GUI Constellation sink plot freez ?

Hello list,

I got questions re the WX GUI Constellation Sink block:

1/ Could anyone give descriptions of what is

* Theta ?
* Loop bandwidth ?
* Max Freq ?
* Mu ?
* Gain Mu ?
* Symbol Rate ?
* Omega Limit ?

2/ What are the essential params of the block to adjust, for my case I am
receiving a BPSK signal (Params @ Tx are: 10 MHz samp_rate, ow_format sc8,
Samples/Symbol = 4, Spread signal with a 11 chips code),

I set:
sample_rate = 10 MHz,
Frame rate = 512,
Constellation Size = 512,
M = 2,

3/ Once the constellation plotted it freezes and "O"s appears in the
terminal section of GRC ?
What am I doing wrong ?

Regards,
