How to temporary turn off seamless mode of VirtualBox?

Solution 1:

HOST KEY + L

OR

RIGHT CTRL + L

is the default key for turn on/off seamless mode for virtualbox

Solution 2:

The workaround for this is to use the other way to nail the window as below snapshot; i.e. using the mouse click instead of using hotkey.

@1 click the Deskpin icon

The cursor turns into @2 and then we click the guest machine, it will be nailed on top resulting as @3

Solution 3:

Here is how i did it:

The win7 start bar was barely visible at the bottom of the screen. All I had to do is click on the part that was visible and THEN press the Host key ( which is right CTRL) plus L.
