Girlfriend started complaing last night that she couldn't click and drag to highlight text all of a sudden. I played around with it, trying different Apps and browsers and seems like she was correct. Restarted and reset the PRAM and still didn't help. Went to deselect the option 'Tap to click' in preferences, and was going to reselect it again when all hell breaks loose. Can no longer click at all, in any way. Can't even find a way to get back into system preferences to reselect 'Tap to click'. Anyone seen this problem before, is there any way out of clickless hell?
