I recently upgraded all my PCLOS boxes to KDE 4. All went smoothly and I'm learning about all the features and am quite impressed with it. There's a setting I'm trying to find and was wondering if anyone can help me out. On one of my boxes, the panel somehow defaulted to a setting whereby when an application is launched and its title appears in the taskbar, when I move the cursor over it, there is a sort of orange/yellow glow that follows the pointer. It's only when moving over the title in the panel. It's really quite cool! How is this feature enabled? I've looked all around but can't seem to find reference for this effect.
