Adrian,

   The value is assigned to config.projname in functions.newFile(). First the
pwd and filename are assigned by the user. Nothing is done to dbFileName
until immediately after that. The functions.newFile() is:

def newFile(self):
   """ Create a new project database file and open it."""
   wd = wx.DirDialog(None, "Choose a default directory:", defaultPath=".",
                         style=wx.DD_DEFAULT_STYLE|wx.DD_NEW_DIR_BUTTON)
   if wd.ShowModal() == wx.ID_OK:
     config.dirname = wd.GetPath()
     wd.Destroy()
     ted = wx.TextEntryDialog(self, "Enter the project name", "New Project Name", "",
                              style=wx.RAISED_BORDER|wx.OK|wx.CANCEL)
     if ted.ShowModal() == wx.ID_OK:
       config.projname = ted.GetValue()
       config.dbFileName = ted.GetValue() + '.db'
       ted.Destroy()

   Originally, the next-to-last line wasn't there, and config.py did the
assignment of projname + '.db'.
