Note: Surfing in Logic can be a little disconcerting at first: moving the mouse to the left moves the editor window to the right, moving the mouse up moves the window downwards... so to get your brain in sync with what you're doing, picture yourself "grabbing" the editor through the window and moving it around, much like you would grab a microfilm and move it around to see what you want through the window.*
Enjoy! *This behavior has changed in Logic Pro 7.1: now you simply move the mouse in the direction you want the window to move, just like a 2D scrollbar.
I just got a mighty mouse. I'm kind of wondering why I bothered, rather than get a regular three or five button mouse from Kensington or Logitech. But I had the old one button mouse before so this is definitely an improvement. The one thing I love now is if I want to scroll smoothly one way or the other in a Logic window, I hold down the mouse wheel (ball) and drag just like I've always done with shift-control drag before. This is way better. You can just nudge it gently and hold the mouse still and watch the window slooowly scroll by if you want. But that right click "button" on the mighty mouse is definitely fiddly, you actually have to lift your finger OFF the left side of the mouse to make the right click work properly! Not the greatest way of implemetning it, Apple.
One thing about the Logitech (5 button mouse) it has this nice feature where clicking the wheel and dragging will also scroll web pages, either direction, in the same manner that this function works in Logic. But I can't get the mightymouse to do that with web pages. One plus with the mighty mouse is the side buttons have become "desktop" with expose.
That right click's a bugger though. Don't like that.
