XnView Software

I've used this tool for a couple of years, and still, sub folders don't sort unless I expand one, close the program then restart it. If I then expand a different folder, all of those sub folders are unsorted (seemingly random sorting) and I have to close the tool and restart it again for that set of folders to sort properly. I'm sure I'm missing something, but I can't find it.

I have the setting 'Folder always sorted alphabetically' checked. I've tried unchecking it too, but there's no difference.

This is on an external, USB connected drive. I don't think it's happening directly on my mac hard drive (but I don't use it as much on that).

MacOS? could you send me some screenshots?

Thanks for the response.
Yes MacOS 15.4
I'm not sure why but it seems to be behaving better most of the time. I did capture this before and after shot a couple of days ago, so it can still happen, but I'm not seeing it as consistently now.

(It's like when you go into the doctor and all of a sudden, your symptoms are gone )

If it starts to happen with the previous frequency I'll let you know, but it does seem better. Maybe toggling some setting ended up correcting it. I'm not sure.
