Description Steve Daulton 2020-09-28 16:49:57 UTC

When running:
 https://github.com/audacity/audacity/blob/master/scripts/piped-work/pipe_test.py
the first command:
 do_command('Help: Command=Help')
fails to print the expected string.


This 'may' be a regression, though I can currently only test back to Audacity 2.4.2.

This bug occurs on Windows and Linux. Assumed to be "all".
