So last night I got my 15" new MBP and I'm loving every part of it. Just have one concern, I didn't have much time to test it out, but I noticed that when I make the windows smaller or bigger (in Chrome, Safari, Finder, etc,) by double tapping or pressing and dragging, the movement is not smooth, at least not as smooth as it should. This is my first Apple machine, so I really don't know how it should be, I've worked with iMacs and old macbooks Pro at work but never really paid attention to this. My machine has 2,6Ghz and Radeon 460, 1Tb SSD. I wasn't doing anything heavy when I tried this, just had couple of tabs open on safari. I'm not sure if I just tried this without the power cable connected, but anyway, this shouldn't happen even if it's not connected. Any thoughts about it? Is this normal? It may just happen sometimes? I just test it for an hour or so. In spite of this I love this machine. Thanks!
