Hello! I'm trying to attach a .pdf file into a note and unable to do so. I've had the same issue others here and in similar threads have stated (can't attach - click on the paper clip, the finder window opens, highlight the file, click 'open', the window closes, and back to the note with no attachment ). I'm on a MacBook running 10.9.1 and EN 5.4.4. Many thanks in advance for your assistance!
