Files listed in reverse alphabetical order

I've already found this topic in older posts.  But the advice doesn't work.

I'm using DW CS6.  All of a sudden, the files listed in the files panel go fro z to a.  I did nothing that should have caused this.   And, I can't find any way to change it back to where the files go from a to z.

I have tried clicking the icon to show local and remote files like was suggested.  All the files were in correct order, but as soo as I closed that view, the files in the file panel were still reversed.  Any other ideas?
