I have been having issues with the start button in windows 8.1 not responding to my mouse clicks. It does respond, but extremely slow, sometimes it takes several clicks and a wait of 30 - 60 seconds for the start screen(modern) to show up. The Start 8 menu seems to work from the Windows key on the keyboard sometimes, but not always either. I do have Start 8 installed and activated. version 1.30.1 is installed. I installed Start 8 last evening on a fresh install of windows 8.1. Is this a Microsoft issue or a Stardock issue? Is anyone else having the same problems?
