Hello, Alt+F4 (also in combination with fn) doesn't close Applications, Explorer, etc. I've tried to change the Preferences --> Shortcut settings, but nothing seems to get Alt+F4 working in my Windows 7 environment. I tried disabling all Windows profile shortcuts, tried other predefined profiles. Nothing worked. It's very frustrating. I'm working with Parallels Desktop 8 (Build 8.0.18354). Does anybody have a clue why Alt+F4 doesn't work?
