I just got my new 17" PB over the weekend, and immediately noticed that the mouse button doesn't work properly. It seems to have spots that click better than others. Sometimes I click right in the middle of the button, hear the audible click, but the click has no effect. When it does select an item, the connection seems to be intermittent. If I'm dragging something it will suddenly be dropped, if I'm selecting an area it will start and stop selecting repeatedly. I've also notices that there is a little gap/unevenness where the top surface of the keyboard deck meets the bottom of the pb, right below the mouse button and above the lid release. The trackpad works fine, it is only the mouse button that has the problem. Is anybody else experiencing this? Should I send it back?
