Hi,
I used Ubuntu 8.04 using ICEWM window manager, VirtualBox 4.2.18 as virtualization tool and Windows XP as virtual guest without a problem. Keyboard shortcuts in guest like for example ALT+F4 closed the current window in Windows XP, Windows_key+D showed desktop etc.

Now I have completely wipe out the disk and install: Ubuntu 14.04 using ICEWM window manager, VirtualBox 4.3.12 and Windows 7 as virtual guest. Now problem appears when I execute ALT+F4 in Windows 7 guest, host OS accepts keyboard shortcut and tries to close whole virtual guest, Windows_key+D hides all virtual machines so again host OS is excepting keyboard shortcuts despite being in a Windows 7 full screen and Windows should accept keyboard shortcuts. This is extremely annoying and time consuming, because I use keyboard shortcuts non-stop.

I don't know where the problem is. Is this some kind of VirtualBox setting to pass all keyboard shortcuts to virtual guest or is this pure host OS setting (like ICEWM window manager)?
Thanks

I have found out a solution it was VirtualBox problem.

In VirtualBox GUI:
1. File | Preferences
2. Input tab
3. Make sure "Auto Capture Keyboard" is checked.

P.S. I remember I have unchecked this settings when having trouble of setting VirtualBox hotkey: viewtopic.php?f=1&t=61824 and just didn't set it back.
