Weird issue on a new Macbook Pro with Parallels 13 running Windows 10. When Parallels is running in full screen mode and I press "command-h" to hide it, Parallels will hide only if there is another application running with an open window on the Mac side. For example, if I have a Firefox window opened, I can hide Parallels. If there are no application windows opened prior to entering Parallels in full screen mode, the white cursor in Windows 10 becomes black but Parallels will not hide. I have to press command-tab and switch to Finder in order to leave Parallels and see the Mac side. Any idea if there is some setting in Parallels or OS X to fix this, or is it a Parallels bug?
