Lo que pasa es que mi proyecto no tiene ese menú y aún asi si lo tuviera no guarda el avance por que no es SCORM, es HTML.
I had this problem as well a few versions ago. Try both collapsed navigation by default and expanded. One of those wroked fine in that previous version, but of course make sure you are up to date.
Some questions for clarification:
It seems to happen only with grouped slides, but I never had the problem. Which exact version are you using? You find the full version number under Help, About Captivate.
Thank you for your time:
Correct, it is only occurring with the grouped slides. version 2019 64 bit
Please, I asked for the full version number, because under the common name CP2019 there have been at least 6 releases. I wonder if you missed an update.
