Thank your for this fantastic editor.  I am so glad to be using TwistedWave.

The function AUTO EXTEND SELECTION TO ZERO CROSSING does not seem to work while the audio is being played.

This is a concern for me because with many cuts to be made in a file, I will make a cut and play over it to check it, and make the next selection while listening to the previous cut.

Thanks,

Mike

Indeed, the auto extend to zero crossing is not working when audio is being played. Thanks for pointing this out. This is now fixed, and the correction will be available in the next update. Until then, you can use the current development version:

Thank you.  Perfect.
