FYI:
There was a MacOS update for both Catalina and Big Sur, some time ago.
And the problem has been reported just after this update, for only Catalina and Big Sur !
So we are presently sharing our mind if this is a MacOS problem (means must be fixed with a new MacOS update) or if the problem comes from our side.
We need your help now (Big Sur or Catalina).
There is another user (on Catalina) who reported the problem.
We sent him these two programs for test :
http://download.thelightingcontroller.c ... w/test.zipAnd we are waiting for the result of his test.
Afterwards, we should be able to know about what to do.
