Thanks for reply J515OP,
Actually I did look this up before I came here and found a Microsoft site which said exactly what you said. So, if I understand this correctly, if I open Windows Explorer via the Modern UI and touch the address bar it should bring up the keyboard - but it doesn't. Same with Google. Nothing happens if I touch the search box. I can see the cursor blinking in the box but no keyboard appears when I touch it. It's probably a setting that needs changing but I've gone to all the obvious places and haven't found anything. Any ideas?
