Multiple Startups

After many, many trouble free years I have now run into a problem which I don't know thing about. When I startup Version 12.24 on Win10 I find the software displays mulitple openings/lister. A dozen or more screens pop open automatically. Any thoughts on the cause and/or resolution. thank you

Is just reopening windows which were open last time it was shut down? Closing them should fix that.

Alternatively, try disabling Explorer Replacement and see if the same folders start opening in File Explorer instead of Opus. If they do then another program or shortcut is opening the folders.

Will try and let you know how it goes. Thanks

That may have done it. I say may as I made one other change at the same time. On the 'Startup' preference I selected 'Don't open any listers'. So I am not sure which new selection was the problem resolution but all is now well. Thank you for your help. very much appreciated.
