Hi. My Macbook is currently clicking on everything. I would try to go click on something, then all the words on the screen would become highlighted in Blue. Also, while typing i will often find it to suddenly become highlighted in Blue then with the next letter click i will loose everything i was typing. This problem used to happen at the starting after i restarted by computer for like a minute, but now it is Non-stop. Also, i feel the thing that you click on to Click is down too far but it won't come back up. How should i fix this Problem?
