To whom this may concern: I was really excited when I found out that emacs 22.1 supports emacsclient on Windows. Thanks for all your hard work. However, I have run into one small problem. When the HOME registry key is set for the local user, the emacsclient.exe and emacsclientw.exe commands both break. If this variable is not declared, then the emacsclient works fine. Copying the .emacs.d/server/server file from the current user's HOME directory to the current user's Application Data/.emacs.d/server directory lets the emacs server continue working. Thank you, Rocco Pigneri
