This is a strange one. Maybe someone can help me with it... I'm a total keyboard user, especially when I'm on my laptop (which is now a Macbook Pro *the peasants rejoice*). But I'm having a very curious problem with it. When I'm in Safari and I use the Back keyboard combination (Command-[), the trackpad freezes up for a second. Not the computer or the application, mind you. Just the trackpad. Everything still works just fine. If I attach an external USB mouse, this doesn't happen (I can move the mouse immediately). This isn't a huge deal or anything, but it is a bit irritating. And it's the only complaint I have about my new computer. So... can anyone shed any light on why this might be happening?
