I have a (seemingly increasing) problem where the taskbar uses the wrong icons for my applications. Simply, grouped windows from an application where the icons differ show only one of the icons (naturally), but the other(s) "bleeds" to totally different applications. I've attached a screenshot showing the problem. This becomes very annoying when not showing window titles in the taskbar, as I have no idea which app I'm selecting. I have Windows 7 Professional 64bit, version 6.1 (build 7600). I don't have any bling installed (I'm a developer and this is my work laptop). Any help would be greatly appreciated!
