I've been using an Apple bluetooth keyboard/trackpad with my laptop for months, but recently, they've both started acting erratically. The keyboard will sometimes send an ENTER command when typing out an address in the Safari URL bar and the trackpad will send a CLICK command often when tracking (I'm definitely not putting enough pressure on the trackpad to click, I've been making sure of that). Any thoughts on how to fix this? I've repaired, replaced batteries, but nothing has worked so far. Thanks.
