So I have recently noticed that the area on either side of the trackpad on my 15" 2007 MBP are acting as a left mouse click when a very small amount of pressure is placed on them. When I say small, I mean the amount you would put when typing normally, so really nothing at all. It's not that big of a deal, but can get annoying when I end up highlighting and deleting something I have typed. Has anyone ever experienced this happening before? Not quite sure what might be causing this. Any help would be appreciated!
