Re: wxColourDialog on the Mac, returning zeros for RGB values, anyone else noticed any issues?

Could be. I've just checked, I'm on MacOS Sequioa (not Tahoe). 

I have the exact same code in two places, one returns a valid colour, the 
other returns zeros for R, G and B values. Absolutely bizarre behaviour 
that I cannot figure out what is wrong.

I've tried all sorts as well (GetRGBA etc etc). The only thing that seems 
to work is if I call some objective C to display the Mac colour picker 
dialog, then the wx one (thanks to chatgpt for giving me the code to do 
this).
