So, I upgraded to windows 10 and for a few days, thngs were going smoothly. Taskbar on my second monitor was hiding as usual, but now, forsome reason, it.... doesn't. It stays up no matter what. What could causethis?

edit: okay, this is bloody interesting. Afterresetting the taskbar, the multi-monitor-taskbar option appeared - it wasn't shpwing before. And now I can enable auto-hide. But, again, I didn't disable it it in the fgst place. So SOMETHING is going on.
