[Seth Johnson <971018@xxxxxxxxxxxxxxxxxx>]

This isn't really a bug in Unity. If you turn off mouse pointer
integration (under the "Machine" menu) to prevent the host from stealing
the focus everything works like a charm.  This means that with pointer
integration enabled and auto hide turned on when the mouse reaches the
edge of the screen Vbox/VMWare decide to give focus to the host, not the
guest. There isn't really much Unity can do about that.

As a workaround you can use: Don't hide the launcher, disable mouse
pointer integration, use <super> to access the launcher, or <alt>+<f1>.

Bug description:
  Ubuntu Precise 12.04 Beta 2 AMD64 DVD:
   
   
  I am running Ubuntu Precise 12.04 Beta 2 in a VirtualBox 4.1.8 session.  VirtualBox Guest Additions have been installed via "jockey-gtk" from the Ubuntu Precise repository, and Unity is running in 3D mode with Compiz.
   
   
  When the Unity Launcher is set to "autohide," the Launcher will never reveal when the mouse pointer is moved to the left edge of the screen.  It does not matter how much "pressure" is applied; the Launcher never appears.
   
   
  I have tried the following VirtualBox window "form-factors," all with the same result (the Launcher never appears):
   
  -- VirtualBox session running in a non-maximized window
  -- VirtualBox session running in a maximized window
  -- VirtualBox session running full-screen
   
   
  I have attached a screen capture (OGV) with Ubuntu Precise running in a maximized VirtualBox window.
