Recreate and display Mz3 book
Usually, an Mz3 book is rebuilt whenever it makes sense and is necessary; e.g. before it is published or if the “Manage Elements” Window is closed.
If you end up with an empty window or a book with 0 pages or alike, making an “Update” using this command often can solve this situation. This command causes a “reset” and recreates the Mz3 book.
These effects are pretty rare but can happen.
If necessary, i.e. when an Update does not solve the problem, please close and re-start mz3Tool.
If that happens often, please contact us and let us know what steps you did so we hopefully can reproduce and solve this effect:
