1. Yeah, I tired it just now. No progress there.
Now for the other two question you'll have to forgive me of my computer ignorance. I'm just a everyday Mac user. I honest am not sure how to correctly answer the questions as I'm not sure what they are asking.
Also I want to note that I am not using a Apple keyboard. I have a Wireless Logitech Keyboard. Now, even with that known, Expose still worked with the keyboard fine till recently. Also I took a close look at the F9-F12 keys and noticed the keyboard has tinny pictures to show what things will open when they are pressed. Of course, when I press them, what opens is exactly what is shown on the keys. Which is annoying. I can't even open my eMacs CD drive with my F12 key as I can only open iTunes' music folder with it. So now it's not even possible (to my basic knowledge) to use my system restore CDs.
