By default emacs in a graphic environment put in the title bar emacs@computer. It’s not a good things when you use the a graphics environment with more than one instance of emacs and try to search for a specific document (ALT+TAB).
It’s possible to have the document name in the titlebar, just put in your ~/.emacs file
(set 'frame-title-format '(myltiple-frames "%b" ("" "%b")))
