Since I started using Windows 7 I have noticed that I am accidentally typing in the wrong window more often than I used to.
Using the Aero theme, the visual difference between the window with active focus and all other windows is quite subtle. Only the minimise, maximise/restore and close buttons go solid and that leaves just the window border and title bar to signal focus by going slightly darker. When apps are full screen you lose all but the title bar decorations, and if you are using a title bar stealing app like Firefox, you even lose that visual cue.
I have tried playing with the settings on the "Window Color and Appearance" page, but disabling transparency takes away much of the prettiness of the Aero interface. Setting "Color Intensity" to maximum gets some of the way but still doesn't leave the active window that obvious.
The traditional way of doing this, setting the colours of the "Active Title Bar" on the Advanced appearance settings... page no longer work as the aero theme ignores this setting.
So, is there any way to make my active window more obvious on Windows 7 without loosing much of what makes aero pretty?
