This concerns the unresponsive or "sticky" mouse button problem common with first run MacBooks. The "fix" is posted here: http://ibloggedthis.com/2006/06/29/...pple-macbook-trackpad-squishy-button-problem/ I've been trying all shapes and thicknesses of paper in the battery compartment under the trackpad. I found one way that made the half of the button closest to the screen work, but the other half was still unresponsive. I tried again a few different times, and now I can't seem to get the button to click at all! If you've had this problem, please tell me specifically what you were able to do to correct it! Thanks!!!
