Can't control width of sr-speedbar

I'm using emacs with sr-speedbar, but can't control its width. When I resize the emacs window, the sr-speedbar always expands with it. I have tried this both with xemacs and emacs.

My .emacs file below:

(require 'package)
(package-initialize)
(setq package-archives '(("gnu" . "http://elpa.gnu.org/packages/")
                         ("marmalade" . "http://marmalade-repo.org/packages/")
                     ("melpa" . "http://melpa.milkbox.net/packages/")))
(setq c-default-style "linux"
          c-basic-offset 4)
(iswitchb-mode 1)
(setq inhibit-splash-screen t)
(load-theme 'zenburn t)
(require 'ecb)
(setq stack-trace-on-error t)
(desktop-save-mode 1)
;(defun toggle-fullscreen ()
;  (interactive)    
;  (x-send-client-message nil 0 nil "_NET_WM_STATE" 32
;                '(2 "_NET_WM_STATE_MAXIMIZED_VERT" 0))
;  (x-send-client-message nil 0 nil "_NET_WM_STATE" 32
;                '(2 "_NET_WM_STATE_MAXIMIZED_HORZ" 0))
;)
;(toggle-fullscreen)
(require 'sr-speedbar)
(setq 
   sr-speedbar-right-side nil
   sr-speedbar-width-x 10
   sr-speedbar-width-console 10
   sr-speedbar-max-width 10
   sr-speedbar-delete-windows t)
(sr-speedbar-open)
(put 'dired-find-alternate-file 'disabled nil)
(add-hook 'shell-mode-hook 'ansi-color-for-comint-mode-on)
;; Single char cursor movement. (assuming you are on qwerty)
(global-set-key (kbd "M-j") 'backward-char)
(global-set-key (kbd "M-l") 'forward-char)
(global-set-key (kbd "M-i") 'previous-line)
(global-set-key (kbd "M-k") 'next-line)
(global-set-key (kbd "M-SPC") 'set-mark-command)
(custom-set-variables

 '(ecb-options-version "2.40"))
(custom-set-faces
 ;; custom-set-faces was added by Custom.

Solution

It consumes variables at load time, not when open.

The sr-speedbar-width-* should be set before the script loaded.
