I am not sure customize calls the right init function when you set the variable like this. If you use just (require 'toolbar-fancy) and then M-x customize-variable RET use-fancy-toolbar RET Select color and Set What happens? What is the color depth of your display? Here at work under the Solaris X server using just 256 colors X emacs is very unhappy with the Next icons. Note that the Next icons use 254 colors (at least that is what the author claims)). At home on a 16bit Xfree86 server there is no problem. Jan
