For a long while now, I have been using my Logitech MX Revolution under Ubuntu/Kubuntu. I have used BTNX to configure it. I am using Kubuntu 9.04.

But recently, I have begun to have a problem using the small button behind the scroll wheel. I believe this is called the Search button.

Recently, when pressing this button, it opens up my browser and goes to a search page. This is very annoying, as I have remapped it to another function I like to use. Does anyone have any idea how to make it stop opening my browser with a search page loaded?
