Objectflow FTX modules causes crash to desktop when alt tabbing?

I've confirmed this is a Windows 8/orbx issue. (i tested the same steps below on Windows 7 with no issues)

On Windows 8 x64 RTM Pro, bare bones.. I ran the fsx setup, then fsx acceleration..

Tested alt enter and windows mode etc, no creashes.. (no ati driver installed thus far either)

then Orbx AU Blue..

It auto prompted to install .net 3.5 and then i reran the orbx au blue. The setup completed.

I then ran orbx melbourne 2.0..

Ran fsx.. random airport.. alt and enter to go window and instant crash on d3d9.dll.

So at this point this proves to me there is a compatibility issue with the orbx ftx objectflow entries in the dll.xml that dont play nicely with windows mode or alt enter to exit full screen etc.

This is leading me to think i may just dual boot and have a windows 7 FSX OS partition for the time being, as i can always port my user cfg files over to 8 if this ever gets a fix. It would be a shame to be flying for a long duration flight and have another app pop up to cause the entire flight / experience to crash in an instant.
