LM14 Cinnamon with VBox Hot Corner

There is a problem with Linux Mint 14 (Nadia) running as a guest OS on VBox 4.2.2. Problem is Hot Corner is activated almost every time move mouse or click anywhere on the desktop.

$ sudo apt-get install dconf-tools
$ sudo dconf-editor 

Uncheck the following properties: navigate to org -> cinnamon -> overview-corner-hover if this does not work

sudo vi /usr/share/cinnamon/js/ui/layout.js

Change reactive: true to false

his._corner = new Clutter.Rectangle({ name: 'hot-corner',
                                               width: 1,
                                               height: 1,
                                               opacity: 0,
                                               reactive: false });
