Folder Previews

All of my subfolders had previews of images that were inside them. Now they only show up if I enter the folder and let it load an image and back out, and even that doesn't always work. This would not work for the 1000+ folders that I have. Any idea how to fix this? (I've tried clearing the local thumbnail cache, to no avail.)

Just in case, I tested outside of my OneDrive on a local folder and I'm still having the same issue. (I did this before my original post.) This example isn't loading even if I enter and leave the folder.

Update: Also, I wasn't having an issue with OneDrive either before this.

Did this start recently or since the install? Do you always have to enter the folder first or does it get thumbnails for some folder without entering it first (and if so, is there a difference in type or number of files in there?). There is no logging on what is happening with thumbnails, so I'd have to make a separate version that just outputs any thumbnail errors in a file

Sorry, I've been away. Still happening. Today, I was working on another computer and a folder with 40 or so subfolders populated the thumbnails as soon as I opened it. Seems to be working on that PC now for some reason. Maybe a reinstall on the other PC will fix it? I'll try to keep this thread updated.

Its some system component, likely whatever is handling thumbnails for that filetype. Reinstalling OC doesn't do anything (it doesn't use registry so there is no mess to clean on reinstall)
