Hello, This morning i started having some issues with my trackpad on my macbook pro. I can use the trackpad and light click, but i can't actually press down and click with the trackpad, which creates a problem when i want to drag. I turned on my girlfriend's macbook pro to check her settings to see what the difference was. She has everything checked in the "two fingers" "three fingers" and "four fingers" categories. However, when i go into my settings to check those categories, i'm not given the option of checking the boxes. I took a screen shot to show what my setting box looks like. How can I check these boxes? Any help is greatly appreciated!
