Hi, this is my first post here, but I'm a frequent reader/visitor of the forum. So I have my first Mac(Mini 2011, 4GB Amd Radeon, $799 model, refurbished) and I notice something that I don't know if its normal on Lion or there's somehting wrong with the mac mini. So basically this is what happens... @ 0:08-0:09 then @0:29-0:30 As you can see when go to full-screen in Itunes, then quit... i get a gray screen(same as the logon screen, and also appears if I launch Itunes in full-screen). When I quit Chrome from full-screen it happens the same plus a black screen. And this doesn't happen in Safari.
