choice is /usr/local/bin/audacity, which is the correct path for 
audacity on my system. As far as I can see, that string has no hidden bytes.

Invoking /usr/local/bin/audacity from the command line launches audacity 
and so does choosing  with dmenu_run. which -a audacity shows only that 
item.

Maybe I need to isolate the function call and start stripping out 
parameters. I should have time to do that later today.

Thanks
