Hide Toolbar doesnt work correctly

[Robin Kluth]

Hey,

My VBox Version: 4.0.4 for MacOSX Hosts.

So, theres a Hide button to hide the toolbar.

In this picture the right top corner: ​http://cl.ly/2K2B2Y2a321i3D0r2S2n

When i click it, it hide the toolbar: ​http://cl.ly/1j2K1N2B0w1f1N281M3R

If I close and restart VBox, it looks like this: ​http://cl.ly/0q2M183R2u3n1X2D0r0b

If I click the hide button again, it hide the empty toolbar, a new click shows it like in picture 1.

So, the hide function does not work correctly after hiding and restart VBox.

It's sine VBox 4 for MacOSX Hosts
