> Audacity 1.3.6-beta Nyquist bug: As soon as a label track is visible in
> the Audacity window, Nyquist plugins do not work correctly any more.
> Bug reproduction:
> 1. I create a Audacity waveform track e.g. via "Generate > Tone"
> 2. I mark a piece of the waveform and apply an Audacity Nyquist effect,
> e.g. "Effect > Utility > Mixer > Cross Fade In" and it works correctly.
> 3. Now I add a label track via "Tracks > Add new > Label track".
> 4. If I now apply "Cross Fade In" again, the old piece of sound in the
> Audacity waveform track doesn't get replaced by the new sound, instead
> the new sound gets inserted at the beginning of the selection and
> everything afterwards gets (optically) shifted to the right.
> This bug can be observed with all Nyquist plugins, even with code typed
> into the "Nyquist Prompt" window but only if a label track is wisible
> in the Audacity window.
> As soon as I remove all label tracks, Nyquist seems to work correctly
Martyn's committed a fix that seems to work fine on Windows (but not
every possible Nyquist plug-in has been tested of course). If anyone
can build from CVS HEAD, please give it a try (and check for stability
undoing the effect, then redoing it with linking off or label track
