Can't change configuration option openSUSE 11.2

I have a minor problem turning on an option for my mouse in openSUSE 11.2. I should be able to click a configuration option my mouse but when I click on it doesn’t change. It’s action is as if option is locked.

When I use gconf-editor it is the same problem. I should be able to toggle from “False” to “True” but even in gconf-editor (Gnome Configuration) it’s action is as if it is locked. All other buttons and choices for the mouse work and/or toggle properly. The problem option is control key press shows mouse location.
