Copying to a USB drive - no progress but file is there

[Tyrannocaster]

Yes, I wondered about rebooting, too. I did, and then copied the file again; this time the progress bar immediately showed 100% but it still says "File operation in progress" with the window open several minutes later. Ah, it just now disappeared; I didn't time it, but it was a long time. I didn't have this issue at all for the first several days I used this OS, and I copied a lot of files via USB - mp3s, videos, and photos, all with none of this.

I'd like to fix this, because the whole idea of using the USB drive is for quick transfer of files, and this is anything but quick.

Thanks for the quick reply.
