Desktop doesn't auto update

Running TF 1.6.17 under 10.9.5 and have noticed a problem where any file saved/copied/renamed to the desktop doesn’t appear automatically. The file appears when I click on the desktop.

It seems the changes are queued as well. I downloaded a file using Chrome and saved it to my desktop. It didn’t appear so I thought the download failed so I downloaded it again, saving to the desktop. When I clicked on the desktop, the first downloaded file appeared. I opened the file and later switched from the app back to the desktop and that is when the 2nd downloaded file appeared.
