My Mac running OSX 10.6 has app that pops up when I hit the F4 key or press the middle of the mouse. I don't know the name of this app and can not find any preference settings for it. The annoying problem is that I bump the mouse in some un-planned way and the app pops up when I don't want it to. 1. What is the name of this app? 2. How can I disable its popping up when I bump the mouse? I would like it to only pop up via the F4 function key.
