Description
Happens starting with 0.4.15-dev-3462-g5dc56dd.
Steps to reproduce:
1. Install ReactOS from Boot CD using VirtualBox
2. Install VirtualBox Guest Additions (all default settings)
3. Restart and make sure VBox VM window is maximized
4. 
Guest won't change resolution automatically due to CORE-17896
5. Open Display Properties (desk.cpl) and change screen resolution to maximum allowed
6. Guest screen will now fit the VBox VM window
7. Close Display Properties and restore VM window to small size (point 4 again)
8. Open Display Properties again and select Settings tab
9. 
Unhandled kernel-mode exception will be triggered
Exception is not skippable, BugCheck will happen anyway.
