Hi, my first post here. I installed ML direct from SL with no problems whatsoever, the whole install took under 50 mins - i'm super happy with it. The 1 thing that has irritated me so far is that if I open one of my non-apple apps like transmission or VLC, even tho I have used them for the first time since my update already, I get that warning box about opening it for the first time again. It's really bugging me after the 3rd time! It's only after I've powered down and up again pretty sure. Why wont she remember I've already used these apps?? Thanks.
