Windows 7 host VirtualBox full-screen crash

I have installed VirtualBox on my main drive. When I run (host: Windows 7, updated) my virtual machine works fine until I try to enable full-screen*. Then it crashes with the following error:

The instruction at 0x00000000 referenced memory at 0x00000000. The memory could not be written. Click OK to terminate the program.

Some info:

  • 64-bit windows 7
  • Intel i7 3630QM with integrated Intel HD 4000
  • Nvidia GTX680M, fully updated drivers
  • AVG free antivirus

I've tried:

  • setting the shortcut to launch in directx9
  • disabling my gtx680m
  • running as administrator
  • edit: trying a different virtual machine
  • edit: disabling my anti-virus

I would love to be able to run any of my virtual machines in fullscreen. Why is this happening?

*My problem is NOT that I can't get the right resolution.

Could also try unticking "Mini Toolbar" in Settings -> General -> Advanced

That stopped the crash on "Full screen" for me - but I still have the other size problem.

I found the answer here:

I have solved this by simply uninstalling VirtualBox 4.3.16, reboot and then install VirtualBox 4.3.12. I downloaded the older version from here: http://download.virtualbox.org/virtualbox/4.3.12/

I was able to "fix" this issue with starting VM´s of Virtual Box (4.3.20) only if Virtual Box itself is in fullscreenmode. VM´s are working then without problems in fullscreen mode too. Anyways - changing the VM-window to another size results in a crash again.
