# Emacsclient uses new instance, weird font

When I open Emacs normally (using `runemacs.exe`), everything appears fine, including the font. However, when I try opening a file in Emacs using the client, while getting the client to start the server itself (that is, using `-a ""`, so e.g. `emacsclientw.exe -a "" testfile`), it uses a new Emacs instance (even if I've already got one open), and also a weird font (currently Sans Forgetica, but previously Minion before I deleted it). I can't find these fonts stored anywhere Emacs would obviously look (I searched both `~\.emacs.d` and my Emacs installation `C:\emacs`), and as far as I can remember have only ever used them once or twice within Emacs a few months ago, when I happened to do `M-: (set-frame-font "font-name" nil t) RET`. The problem goes away when I restart the server within emacs by doing `M-x server-force-delete` then `M-x server-start`. What is happening here and how do I fix it?
