Was happening in 3.11.1 (and well before that), still happening in 4.0.1. It was solved many moons ago in the old forum but has been back for quite a few years now.

When using Traktor in Full Screen view, macOS puts Traktor into it's own "Space" and when you move back to the Finder "Space" for example, to look through tracks or transfer files … or if you have something like Maschine or Ableton open, the screens on the D2 controllers freeze up.
This also happens on the S5, and I can guess it happens on the S8 as well (I do not own one but can get a friend to check unless anyone else can confirm).
AND … the countdown time on the X1mk3 that I just purchased also freezes up.
Please once again fix this issue. Thank-you.
