I have a Macbook Pro, works sweet up until yesterday. If I am on my desktop and use my touchpad to move the arrow across the page, it will 'pick up' and drag a box as if I have also clicked down on the clickpad. It highlights text I am reading/writing and also to access anything where I would usually click once, needs a double click. I have tried cleaning around the touchpad with an edge of paper. I think the click must be activated someway without me touching it. Does anyone have any suggestions?
