10.6: Replace Exposé's blue 'glow' outline effect

If you dislike the blue glow around Exposé windows in Snow Leopard, here's a simple fix.

Go to System » Library » Core services » Dock » (Control-click and choose Show Package Contents) » Contents » Resources. There you will find two files: expose-window-selection-big.png (for normal windows) and expose-window-selection-small.png (for minimized windows below the horizontal line).

If you change the color of these pictures in some image-editing program that preserves transparency, it will change the color of the 'glow' effect. Tip: To me, it looks the best if you use white, but pick whatever you like.

[robg adds: While this works, note that it breaks code signing on the Dock. This may or may not cause problems -- technically, I believe it means that the Dock no longer has access to anything in the keychain. Whether or not the Dock needs such access, I don't really know. But I tested this, and with the modified resources, code signing on the Dock is definitely broken. More info on code signing.]
