Just wondering if anyone else had experienced any problems with the trackpad? Having returned the first custom specced 2.9ghz i7 I have just received a second and the trackpad on both have had the same problem. At certain times in certain areas the trackpad will not click i.e when you try to click the trackpad is rigid. On the first laptop it seemed to be in the lower left of the trackpad and this time it's in the middle on the right. It is not consistent but easily reproducible. I have arranged to return the second one, with the third currently on order, but obviously I am worried this may be a design fault. I'm going to an Apple Store to try the standard spec one tomorrow but wondered if anyone else had experienced these problems?
