This is really frustrating me, I hope someone has a solution. I'm on macOS Sierra, Windows 7 under Parallels Desktop 13. If I'm in any Windows application, hitting the Command key once will bring up the start menu. But if I'm in any Mac application, hitting the command key once does nothing. The start menu cannot be brought up by the keyboard unless a Windows application has focus. This makes it extremely frustrating if I just want to quickly do something in Windows while I'm in the Mac, since the Start menu is usually the quickest way to get to whatever I'm ultimately after (searching for a file, application, opening control panels, etc.) Is this intentional behavior (locking out the Start Menu unless Windows has focus) or is something configured wrong? Does anyone know how to fix this? Thanks!
