Sorry for coming back so late on this subject, but it took my a while to enable the D3D-support in Virtualbox.
In fact I had to switch back to Windows 7 in order to get in running.
This time the visionaire editor started and I was also able to switch between the different editor interfaces (scene editor, character editor and so on...), but I ended up at the same situation that von Lebostein described: None of the grafix are display and if you switch editor panels 3 times or resize the window multiple time, the editor crashes with a coredump at the location AFRLme descripted.
Interesting: During editor panel switchting or resizeing the grafix are flickering through - but in a very distorted way (looks like that the bg-buffer is completly messed up)
If you want, I could sent the zip-file with the crashdump.
