problem with mail .mp3 attachments
I can't figure out how to fix a lock up with mail when I try to attach an .mp3 file in mail 7.1 on Mavericks 10.9.1. Whenever I try to attach an .mp3 by dragging or using the "paperclip" I get a green + "copy" sign and then the beach ball, which never goes away. It is only a problem on my macbook pro. My iMac has the same versions and is just fine. I only have noticed problems with .mp3 files. I have no issues with anything else I've tried to attach.
OS X Mavericks (10.9.1)
