Question: with two Chessbases open (1 for live games and 1 for analysis), if you want to "copy a position" the software automatically opens the "insert" window (x). Problem: it must be closed otherwise the analysis engine no longer works and it is no longer possible to navigate through the moves of the game.
Answer: it helps if you disable the following option:
Menu File - Options - Misc - "On New Game open last game".
