This new feature doesn't work for me in Parallels. Moving the mouse to the bottom of the screen doesn't cause the task bar to appear. I checked the settings and Show Windows Store Apps on the Task Bar is checked. Tried it with Windows running in an OS X window and running full-screen. Going to the top of the screen in a Modern app brings up the new controls for it. Current version of everything running on a 2012 Mac Mini. Any suggestions?
Looks like Parallels don't care about this, and others, problems. I don't see why I need to update to from 9 to 10 if the new version still have this problem, and other ones. I want this problem solved and I will note update until I get it.
