I put let g:Netrw_list_hide= g:netrw_list_hide into
the 'wrapper' function that saves the session.
"" Save session after confirmation
function! TjSaveSession()
let g:Netrw_list_hide = g:netrw_list_hide
let res = input("Save Session: [" . v:this_session ."] (Y/N)")
if res == "y"
exe ':call AutoSaveVimSesn()'
endif
endfunction
"" Global variable saved

And the line above in my .vimrc
