Q: I am unable to attach audio and vido files using mail after I upgraded to mavericks.  10.9.2 2x2.4 Ghz qyad core intel Xeon

Has anyone found a solution for attaching video and audio files in mail with Mavericks.  It works fine on my macbook pro but does not work on my desktop.  I get the spinning wheel of death.  It worked fine before I upgraded to Mavericks.

2x2.4 HGz Quad core Intel Xeon, 12GB 1066 Mhz DDR3. 

Thanks

Tom
