In 3.x it went fullscreen on the exact monitor the windows was beforehand. Now I have to make the external (projector) screen the main one, fullscreen the vm and then take the main screen back, so the host programs open new windows on the laptop screen. This makes VirtualBox almost unusable since this is a real hassle not only when setting up the projector the first time. Now, when the vm reboots (still in fullscreen) and the vm additions kick in to change resolution, they take the resolution from the main screen, which is different from the projector.. Sorry: absolutely unusable. Furthermore if the fullscreen vm has focus, menubar and dock on main screen get hidden, which, too, has not been the case with 3.x. Please change this back. ;-) Please do not hesitate to ask for further information. VB is a great product, I'd really like to help. :)" defect closed other VirtualBox 4.0.2 obsolete marc.horstmann@… Windows Mac OS X
