I am happily enjoying my new 13" MBP but I do have a couple issues that I am seeking some clarification about. When I browse through finder in the cover flow view, about 75% of the time the icons of the files will flash between the icon and a blank icon image. Is this normal? Is this a result of the graphics card, the hard drive, or something else? I did a search earlier and read that it may be that the stock drive cannot write the images fast enough when scrolling. Any validity to this? Also, when I view the iTunes visualizer, at points when I freeze the vizualizer (hit F) and the camera zooms into a bright section, the screen flickers, as if it cannot handle the "explosions" of light up close. Is this normal and is this the result of the 9400m? Would upgrading to a WD Scorpio Blue solve either of these problems (particularly the cover flow icons)?
