I must of spilt a little bit of something sticky on my trackpad a while back, but now it's acting up. Right now it still registers like I can move the mouse and stuff and I'm able to left click although it isn't as "clickable" as it was before and left clicking isn't working. Is there a way to clean the stickiness? I'm at a university with no close apple store by and our campus computer store charges a ridiculous amount. Any input would be great! I have a MacBook Pro is one whole track pad. There's not distinct buttons for right and left.
