10.6: Snow Leopard update remaps mouse click
10.6: Snow Leopard update remaps mouse click: “The latest Snow Leopard update (10.6.4) remapped the right mouse key to Application Switcher for the Apple USB Mouse when I applied it.
If you are surprised at having the large dock style transparent window suddenly popping up in the middle of your screen, simply go into System Preferences » Mouse and remap the right mouse button back to the Secondary Button (which was the default).
This will also restore the mouse’s right-click functionality within your various applications.
[crarko adds: I haven’t tested this one. Can people confirm that this happens with 10.6.4?]
