I've set up a multiple-monitor system and in general it works well. However, when I move my mouse from the left monitor to the right, I have to do it very quickly. If I move it slowly, the pointer "sticks" at the border. There must be some setting to control this, but I have no idea what it would be called or where to find it. I have browsed through the ATI Catalyst Control Center software for my graphics card and do not see a setting for this.
