Has anyone else experienced this? Using my 13" MBP (2011) with Snow Leopard, I could connect it to my 27" Cinema Display, in clamshell mode, press the space button on my wired external keyboard and a picture would show on the Cinema Display within about 3 seconds. Since installing Lion, it takes about 15 or more seconds to show a picture on the Cinema Display. Worse, it then doesn't connect my bluetooth mighty mouse and the only way to get it to connect it to use a wired mouse and to manually ask the MBP to scan for bluetooth devices. It finds the mouse and connects. I can just about live with the slow reaction of connecting the Cinema Display to the clamshell 13" MBP, but not recognising my bluetooth devices is a massive pain. I don't want to have to find and connect a wire mouse every day!
