Hi all, first of all I'm very new to macs and I love it! I'm an amature photographer that is getting paid sometimes to do portraits and stuff... I've been using windows forever... I just got a 17" macbook pro to do my edits with LR2, my problem is my just scrolling the images itself, I can't stick to one image. Even on iTunes, if I move the mouse towards the top, iTunes will automaticaly decrease the volume to zero. I'm using a wireless laser USB mouse, or is it the track pad?
