With great difficulty, I found the old version 5.9.6 in the archives! Oh my God, how it was a long time ago Deleted 10.4 and rolled back to the old version. Working at 10.4 is not possible! Base and errors start slowly. Very bad. Excuse me!
Immediately after installing version 10.4.4 build 2096 public
there were duplicate notebooks. And in the web version they disappeared. Synchronization doesn't help. How to solve a problem?
