Unity takes keyboard focus when in Virtualbox guest

[aproposnix]

Ubuntu 12.04 (64bit) - latest updates applied
Affects Unity 3D (not tested on 2d)

Issue Summary: When using virtualbox (VB) in fullscreen mode, VB takes control of the screen. This means that even though the Linux host desktop is locked I still am able to function in the guest OS without having to log into the linux host (when the screnesave lock comes on).

The problem I have been faced with over the past few months is that whenever I lock the VB guest (it's windows, so I'm using Alt-L to lock it) it activates the Unity Dashboard in the background. What happens then is that when I come back to my computer I log into windows but the password is actually being written to the Unity Dashboard. I've had it happen already a few times at work where I had people standing around and my password was exposed to them.

Expected behaviour - Virtualbox should have control of the screen until I either minimize the VB or I close it completely. Instead of this, sometimes the host OS is taking over the keyboard in the background.

As long as "Host key capture" is turned on in Virtualbox, Unity shouldn't get the Alt key presses in the first place. Can you ensure that setting is on when you face this issue?
