tkSimpleDialog window focus problem

[inkhorn]

Hi all,

As part of the program I've created and am maintaining, the user has
to type in his/her username and password into tkinter simple dialog
windows.  What you'll see below is that I've nested an askstring
dialog window within a call to use the ftp module to login to an FTP
server.

result = self.ftp.login(self.userid, tkSimpleDialog.askstring
("Password Entry",
                                              "Password:", show="*"))

Annoyingly, every time this password entry window pops up, the focus
does not go on it automatically.  Anyone know what I can do to put the
focus on it automatically, while *not* storing the user's password in
my script for the remainder of its runtime?

Thanks,
Matt Dubins
