(I don't know what happens but messages are shown empty (even aften
writing text inside).)
----------------------------------------------
I don't know why I had argdel * after mksession.
...oh...maybe I know... not enouth knowledge of vim :)
I found a new way to integrate argdel:
augroup SaveRestoreSessions
autocmd!
autocmd VimEnter * nested source $VIM\vimfiles\sessions\Session.vim
autocmd VimLeave * call MakeSession()
autocmd VimLeave * nested mksession! $VIM\vimfiles\sessions
\Session.vim
augroup END
function! MakeSession()
if argc() != 0
execute 'argdel *'
endif
endfunction
