i bought my alu macbook the day it came out and didnt have a single problem until maybe 2 weeks ago when the trackpad got all messed up. i didnt do anything, it just happend. i have been using just a USB mouse because i havent had time to fix it. but what happends is, when ever i just put my finger on it, not even click down, it will register as a click. and then when i move it, it will look like im selecting everything, like highlighting it. this is very frustrating because i have NO clue how to fix it. all of its updates are up to date too. please give me some help. and if someone suggests re-installing leopard, when i do that would that delete everything on my hard drive? cause thats why i haven't tried it.
