The only way I've found to fix is sending from guest menu Ctrl-Alt-Del and choosing start Task Manager, doing this will return to work properly until next screen savings. Disabling screen savings also prevents the problem but the bug still exist. Note: On both machines direct 3D support is enabled with WDDM and has been running with this configuration for several previous versions without problems." defect closed guest additions VirtualBox 4.2.18 obsolete """screen savings""" Windows Windows
