This problem just resurfaced for me in 4.2 (I was not experiencing it in 4.1) ...

[Intel 3770K processor, Nvidia Geforce GT680 2GB video card (latest drivers) ..]
Windows 7-x64 Host, Windows XP-32 VM (all windows VM's crash the same way though).
I have the VM configured for 2 displays.

Switching the VM in- or out- of full-screen mode (or seamless mode) causes a crash.
Changing acceleration and video memory settings make no difference, however it does not crash while only using 1 display.
Has anyone else started to experience this again in 4.2? I know there was a similar issue in previous versions.
EDIT: I've downgraded back to 4.1.22 since I really enjoy using 2 VM displays... (Still have the 4.2 Guest Additions installed in the VM) ... And confirmed there's no more Full-screen toggle crashing.


Seems like there's nothing particularly useful in the log at the time of switching in/out of fullscreen mode:

bump... Multiple host screens still crash in 4.2.4 when switching into/out of full-screen mode.

Hi,

Happens for me even when the guest is not full-screen. I use 2 monitors at work, with VBox open on the main monitor in a maximized window. When I switch to single monitor profile (using NVidia Desktop Manager profiles), VBox crashes. Happens both in 4.2.2 as well as in 4.2.4. Did not happen in 4.1.x. Guest is Linux Mint 13 and/or 14.

Tested this again on 4.2.8 ... Still crashing... Would submit a bug if I knew how..
