Keyboard Firmware Update Arrives to Fix Problem
I've noticed this issue with my MacBook Pro's keyboard ever since the update with Leopard - if you let the machine sit for a bit, no need to let it go to sleep, just let it sit for 5 mins, and then hit the keyboard, the first key will be ignored. Seems I'm not the only one to notice. The friendly guys at Apple have seen this and released an update.
One of the most interesting things about this update is that it requires no reboot in order to be put in place. Pretty slick. I should be able to see the difference today, and I'll sure be looking, but I'm guessing the problem is fixed - which is just great.
