Spectrum Editing - Frequency Selection Playback NOT WORKING - Wavelab 12

Hi

I am also running a reasonably fast Windows 10 machine (current update) with 32 GB of RAM and the current WL 12 version.

This works as expected here with and without plugins. I also tried M/S and that also worked as expected.

It follows that I have nothing useful to add except that I agree it looks plug in related.
