Hi, When typing anything, the letter you're typing usually lights up in green, so you know you hit the right one. A few mins ago I was typing something and it seemed to stop doing that mid-sentence. I figured I'd accidentally switched something off. When I hit the little "cog" icon to go into the settings, I don't find one relating to that. It still vibrates with each keypress and there's a setting option for that. I read through the instruction manual as well and didn't find anything there either. Anyone??
