I have the official weirdest problem in history. Crappy old I5 HP Laptop with Win 10 installed. Everything works fine BUT - The left touchpad button will not activate the start button (The little 4 window icon at the bottom left). In other words, I can't get the menu to come up with the left touchpad button. THe button works fine every other place on the PC. A mouse attached works fine. I've deleted the touchpad and reinstalled it. I found a newer driver and installed it. I went into mouse settings, everything good. I went into the ease of access section to see if anyone had screwed with it. I looked in Programs to see if any weird program had been installed recently. It has nothing but the essentials and MS Office. I can find absolutely nothing in research that mentions this particular problem. I'm feverish with a cold and the only thing that is keeping me from jumping out the window is that the window won't open. My last ditch effort will be to reinstall Win 10 but that seems pretty wild. Anyone have any other ideas? I've already jpeg'd it too.
