I bought the 2011 13" MBA online (Apple Store) the week they came out. Straight delivery from China. Returned first order, settled on second assuming I had problems adjusting to it. Appears there's something more to it. There's a click-issue, where the operating system / hardware does not detect clicks. It does not matter if I use the MBA's trackpad (click or tap) or an external Magic Trackpad. At random intervals, occurring daily, clicks will not register for a second or three. How would I go about troubleshooting/repairing this MBA? I'm located in Finland where there are no physical Apple Stores, only authorized resellers.
