Cursor changes color after code completion

[ericho]

Hi,
I just installed emacs-for-python on emacs23 but after write some code and gets the code completion the cursor changes to black color (the same as my background).

This is the content of my .emacs file.

;;; uncomment this line to disable loading of "default.el" at startup
;; (setq inhibit-default-init t)

;; enable visual feedback on selections
;(setq transient-mark-mode t)

;; default to better frame titles
(setq frame-title-format
      (concat  "%b - emacs@" (system-name)))

;; default to unified diffs
(setq diff-switches "-u")

;; always end a file with a newline
;(setq require-final-newline 'query)

;;; uncomment for CJK utf-8 support for non-Asian users
;; (require 'un-define)
(custom-set-variables
  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 )
(custom-set-faces
  ;; custom-set-faces was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(default ((t (:inherit nil :stipple nil :background "black" :foreground "white" :inverse-video nil :box nil :strike-through nil :overline nil :underline nil :slant normal :weight normal :height 120 :width normal :foundry "unknown" :family "DejaVu Sans Mono")))))


;(add-to-list 'load-path "~/.emacs.d")

; cscope 
(require 'xcscope)

;(menu-bar-mode 0)
(setq make-backup-file nil)

(load-file "/usr/share/emacs/site-lisp/emacs-for-python/epy-init.el")
(epy-setup-checker "pyflakes %f")

Do you know if this is a problem or just a misconfiguration on my emacs setup? I need the black background due to my bad vision.

Thanks in advance!
