So what you're saying is that it's the version of wxPython that was  
working or not?  I'm using 2.6.3 as installed by DarwinPorts (from  
source), and it does just fine (though slow; more below on that).   
Any other OSX users of GR using 2.7.X successfully?

When you say "wonky" what exactly do you mean?

I know that the GNU Radio GUI stuff is -slow- on OSX because it does  
wx(Python)->X11->Aqua/CoreGraphics, and the "X11->" part is a big  
bottleneck.  Linux has faster graphics because it uses native X11  
processing.  In theory it would be possible to create a module for  
"gr-gui-osx" (and thence "gr-gui-wx", "gr-gui-window" and such via a  
means similar to gr-audio-*), and then all of the GUI's would be  
native to their host, which would certainly speed things up for OSX  
(and I would presume Windows too).  That would also mean rewriting  
any GUI stuff for a common API which would be supported by all of the  
GUI modules ... which IMHO is certainly doable if anyone wants to do  
it.  Has anyone thought of this aspect of GNU Radio?  Certainly seems  
like there are other OS-specific modules and/or sections, so why not  
for the GUI as well? - MLD
