Mr Grim, dont think so. Total Commander, AbiWord, WinRar, other apps are the same. In Vista I had the same issue, but I found some visual style that changed it. That light blue I think is system wide color for vista and 7. Now I´m using a theme that includes a visual style that corrects it, but I dont like the theme very much. All the themes I have found till now are only variations of aero. None are better than the original one tweaked by me. But all those themes have that light blue. When you use a blue theme its ok, but I like my themes more grayish because I use very "strong" backgrounds.
The idea would be a visual style that has sort of XP colors, gray/silver or like MS Office black theme.
BTW: thanks for answering and caring
