Hello. I can't find the place to pose my question, so you are the lucky person. I have a 2011 MacBook Air. I no longer seem to be able to use the trackpad to scroll smothly up and down the screen. It seems to "stick," or slowly jump in the direction I want to go. The arrow keys move the screen up and down smoothly. Any ideas?

And now the battery only lasts a couple of hours. I guess I'll just use it as is. Battery replacement in Mexico, where I live, requires $50 worth of to and fro shipping, but the cost of a new battery installation. Any comment? Thank you.
