What on earth is this post about-i hear you question....
I've just done a clean install of Nis 2012 (ran NRT after removing Nis 2011) and i have noticed that when i press performance on the GUI a new window opens up- not the flipping action that happened in Nis 2011.
Now i know this isn't the most important aspect but i happened to like it in Nis 2011 and i cant believe its been removed (also a beta Nis 2012 video on youtube show the flipping window 
in the product).
I am running windows 7 64-bit with desktop aero enabled (so its not that) and the latest Nvidia drivers......any ideas....does it flip in your version?
