Bug in latest release. I just installed Cakewalk_by_BandLab_Update_Setup_26.10.0.075. After installation recording did not function correctly.
I put an audio track into record as per usual, pressed R, played for a while. On pressing STOP, the recording disappeared with no indication of a recording in the history. Tried a restart etc etc, still the same.
Wound back to previous release and all is well.
