Do you have this problem without theme atlas ? For the glow it's normal because all windows with ribbon (like explorer, paint, wordpad...) don't use theme atlas glow but another in the theme file but the Windows 8 Aero theme don't have any glow effect so, if you want glow, you must use 3rd party themes on your computer. Thanks for your reply. 1 - How to setup without theme atlas? Do i need only to delete the png file or have I to edit registry or else? 2 - Can you give me some directions to look for theme having both round corners and title glow effect on all type of windows? I use this theme which makes it look exact like Windows 7 with glow and round corners http://xxinightxx.deviantart.com/art/Aero-8-1-Windows-8-1-413881040 Many thanks. I did it and everything now is ok...but first of all i had to delete the atlas png from registry.
