I erased dropbox, but trash says it is still in use
I have been trying to clear the dropbox app on my computer. I followed the directions provided by dropbox but when I empty the trash can, I get a prompt that the application is still in use. I have restarted, no change. I cannot find anything actively using dropbox. Any ideas?
