color-theme problem

[Ohadi, Hamid]

Hello there,

I have got the color-theme.el in my load directory and I'm able to pick up a
color theme and install it by loading the library and then selecting a
theme in emacs. However when I put the

(load 'color-theme)

in my .emacs configuration file to install a theme permanently I'm given this 
error:

setq: Symbol's function definition is void: color-theme-filter

Sorry to bother you guys but I Googled it and it came up with nothing.

Regards
Hamid
