Thanks John for your response. Sorry I took so long to respond. Your button #3 I had not considered, but I don't remember that I had scrolled the tracks up.
I'm just getting re-oriented to the Magix terminology. This is my 3rd version, the first running under Windows 10.
First, I've got three slideshows in a single project and they're all three loaded when I am editing any one of them. The first time the timeline went away it was only for one of the slideshows. The second time, they all went away. One thing I remember from the old days was that some problems were dependent on the number of pictures, videos and titles in the slideshow/project. I have a lot of objects in these three shows.
On one occasion I left the project open with the program running and went to eat dinner. When I came back, voila, there were the missing timelines. I assumed the program was still churning along and finally finished.
I have always saved my projects after any significant change. Now I am saving after almost every change untill I am more sure of the programs' operation.
You seem to have a good level of knowledge regarding this program. I hope that I can look forward to furure advise.
I've always had issues with Magix's documentation styles but I understand the issues of clearly describing complex software. I am now looking into splitting each of my current 3 slideshows into at least 2 separate slideshows. It's a little more involved but should be more manageable. I'm using very small numbers of objects to get the process down before I chance the "big bang".
. . . . I've got three slideshows in a single project . . . .
I presume as three seperate timelines.
If so then the easiest way to do this is to create three seperate projects, and complete all editting in all three.
Then create a fourth project, importing the individual ones previously created - using File, Open project and when prompted select Add to project.
This also makes it easier if you have to go back and edit one of the parts - however you do have to re-import a changed project and remove the old version from the complete project.
To split the current project with three slideshows - save the project 3 times with different name eg . . . . Part 1, . . . . . Part 2 etc.
Open each part individually and delete the timelines not required and save - repeat for the other parts.
