Hi,
If I launch gr-digital/examples/ofdm/rx_ofdm.grc using
gnuradio-companion, it runs a barely visible window that is probably a few
10x20 pixels in size, and if you maximize it, the window is empty with no
controls.
This is with the gnuradio-3.7.1 release.
Best regards,

Hi,
I have a USRP2 + WBX board, and would like to use GRC to simultaneously
transmit and reveive OFDM using a single unit.
Is it possible to have a single GRC file launch two windows and run the
transmission and reception using a single WBX board at the same time?

Hi Josh,
WxWidgets 2.9.0 supports Cocoa on Mac OS X 10.6.4, so if I
