Fixed in 0.9.17 by John Popplewell:

Lockfile (that prevents multiple launches) is now stored in the user's local temporary directory on Windows (usually 'C:\Documents and Settings{username}\Local Settings\Temp'). This allows multiple users on different desktops to use a shared save directory on a network drive, without having to disable the lockfile feature, or wait for the lockfile to expire.
