Dragging file to desktop creates empty SFTPDROP

What causes this? I used to be able to draga file from an FTP site directly to my desktop. Now, when I do it, I get a empty folder that is named SFTPDROP? What causes this, and how do I fix it?

I have uninstalled and re-installed twice. But with no luck.

Thanks!

Doug
