Regression: WDDM crashes during assessment test ==> Fixed in SVN

[Michael]

VirtualBox 4.1.4 allowed me to use Aero. After installing VB 4.1.6, the extensions, and guest additions, Aero no longer works. The assessment crashes. Windows reports the following error:

We've fixed some additional issues that caused WinSAT crashes here. Here is a test build of Guest Additions that contain fixes: ​http://www.virtualbox.org/download/testcase/VBoxGuestAdditions-r74773.iso
In case WinSAT still crashes for you, please attach crash dump files here. See https://www.virtualbox.org/ticket/9267#comment:36 on how to enable dump files generation.

I installed the additions you linked. The assessment test now runs successfully. Aero also works. Thanks.

Great to know, thanks for the feedback!

These fixes should be part of VBox 4.1.8.
