Pressing Windows key will trigger the menu, then immediately close it
Oftentimes, when I'll press the left hand Windows key to trigger the Start10 menu, it will open then immediately close (almost as if flashing). In order to fix this, I have to use shift+click to remove this behavior. I've noticed this happens a bit after my computer is locked.
I'm using DisplayFusion (if this is worth mentioning) to draw my toolbar on mutli-display. This doesn't happen every time but enough to drive me to be frustrated
