I'm having a lot of fun playing with and learning my new SP4. This is my first tablet and my first Win 10 PC, so there's a lot to learn. By far my biggest frustration (and disappointment) is the unresponsive screen for both touch and the pen. Sometimes when I click on a link, nothing happens. This happens way too often. Then I click on it again and again and, more often than not, something finally happens. I'm pretty sure I made contact each time because I see the screen react to my touch or tap of the pen. Is this a software or hardware issue? Or both? Do you think this will be solved with future software updates? Is there something I can do now to make it better?
