Next time I will open my eyes bigger haha Thank you ace2! Edit: Ok, it look impossible to find out the lines you are talking about - on post #402 -. I mean, i'm started from the default "aero.msstyles" and it have around 4500 lines... I've download some softwares to do the job I expected, but nothing works... The only solution I see, is to find a Windows 8.1 and install it, but I don't want to, because all works really great now, and I don't know nothing about stablility of my programs running windows 8.1. So another working solution? http://www.msfn.org/board/topic/163794-aero-glass-blur-tweaker/ http://www.msfn.org/board/topic/170384-aero-glass-cofigurator-for-windows-81/ http://www.msfn.org/board/topic/162036-aero-glass-tweaker-gui-for-win8-v132/page-13
