Description

I follow my post about the problems of the graphic driver on Windows guest to advise that finally the new VirtualBox 4.3.20 Linux Guest Addition is buggy. Installed on a Windows 7 64bit guest the system slow completely down becoming hardly usable.

My configuration:

Laptop i74500U, 8gb + external monitor 1920x1080 Host: Fedora 20 Guest: Windows 7 64bit SP1 and recents updates

At the moment I downgraded to version 4.3.18, and all is magically back running.
