click pad/touch pad issues

[headviking]

I have a 4 year old macbook (black). Sometimes the click pad/touch pad will double click (two finger) or click whenever I pass over a link. Is there anyway I can fix this on my own? I have opened and replaced laptop parts (memory, hard drives key boards), but on window based laptops. Do I have the knowledge to accomplish this issue fix?

I can't believe I am the only person with this problem. Anyone? I have removed the battery and blew out any dust that may have gotten in. I did the same from the top as well.
Can anyone help me?

Found the fix without anyone even replying to my request for assistance. Gee thanks. I guess I'll just keep the fix to myself, because it's clean now-one seems be interested.
