We have that set.  So when we wanted to use it as a "save as" dialog we 
needed to allow the user to type a new filename so we were grabbing that 
directly and returning it with the path selected in the dialog.
This seems to work now when AnyFile is set.

This was written some years ago so I can only think that either setting 
AnyFile somehow didn't return the user's choice or there was a bug in 
some particular version.
