Finder forcing focus

I just restarted my Mac and now the Finder keeps grabbing focus every few minutes. I see where others have complained of this problem but I have seen no solution whatsoever. The suggestion is to restart, but the problem started after a restart! It doesn't matter what application I'm in, Finder will grab focus. I've been in Safari, Chrome, Pages, Mail, and iMove and had this issue. What the heck is going on here???
