This is my first time purchasing an Apple computer. Its a 17" MBP Penryn with the LED backlighting from Apple in the mail today. Its beautiful! But I need some quick help: 1. On the bottom of the screen where it says finder, dashboard, email, safari, ichat, etc.. How do I add the AOL and Yahoo Messenger Icons (i downloaded the software and it works)? The icons for AOL and Yahoo Messenger only display down there when I open the program. Once I close the application it removes it from that row of icons at the bottom. I'd also like to know how to delete some of them? 2. How do I right click? I tried putting 2 fingers and clicking but nothing displays. 3. How do I check the temperature of my laptop like many of you do? Is that a program in the computer already? It got hot really quick on the left speaker side and the bottom of the screen when I first turned it on and is still hot. The bottom back side is also hot. 4. Finally, I would also like to know how to set the mouse pad to click on an icon, for example, via double-tapping (rather than clicking the plastic tapper in front of the mouse pad)? Thanks!!
