Hello MacRumors! As some of you might be aware of (but your probably not) i have replaced my iMac with a Mac Mini 2,6 GHz i7, 10GB RAM, 1TB 5400 RPM drive and a LED Cinema Display. Sadly i have noticed that it is "lagging" while displaying certain UI elements. Scrolling in Safari is jumpy and the dock is glitching out. Im not sure where to go from here. Is it the HD4000 that can't support the Cinema Displays resolution or is it maybe the wireless mouse messing about? Any help is appreciated.
