Issues Saving Session Files in Audition.

Hello,

This has been happening to me for years. I don't know how the issue of "Save As" not saving Multitrack files. In the past, I used to put my laptop to sleep after I am finished. Now I can't.

Today, I found out that my last Multitrack save (I'm in the middle of it), didn't save any of the files of my podcast that I added. I had to put them in order again. 

How do you save Multitrack files? "Save As" doesn't work anymore. And why doesn't Audition save Multitrack files automatically like Premiere Pro does?
