Saving Tabs at Startup


I use OPUS 12 recently and every time I open Opus I had the same open tabs as when I had closed it.
But now when I open Opus the tabs are empty !! Why?
How to find the open tabs with the list of folders and files?
I have not changed anything in the settings menu that could explain this.

Thanks for your help and sorry for my English

Assuming you're using the Pro version, what is selected in the pages under Settings > Preferences / Launching Opus?

I put the screen shot
Thank you

Is Preferences / Launching Opus / Default Lister / Update Default Lister automatically when closing a Lister turned on? Try turning it on if it isn't.

It is already activated ...

How are you opening the new window(s)?

I do not understand your question, sorry
After every restart of windows 10, when I open OPUS, the tabs are present but they are empty!
How to find them like before closing windows?
You understand ?

How are you opening/launching Opus? (There are a few different ways it can be done.)

I open it by clicking on the icon on the taskbar


My problem is resolved.
I put OPUS in automatic start with Windows and since the tabs are full.

Thanks to all
