Undocking Cured with Win8 & DX10?

Hi ...was wondering if anyone has tried and had luck with Win8 curing the un-docking of windows issue in DX10? Where if moving the un-docked 2D window to a 2nd or 3rd monitor causes it to black out.

This issue was referenced a while back in the following thread Jim started (but I couldn't get any of these suggested fixes to work on my setup):

http://forum.avsim.net/topic/386154-dx10-preview-fsx-opens-on-wrong-monitor/

I've seen comments that win8 has helped with other issues, so just curious about this one since it's really the only thing keeping me from a full switch to DX10. I need to use my Realityxp 530 un-docked on a 3rd monitor and it's kind of a deal breaker, unfortunately, since I've seen no sure fix for the 'window black-out' problem yet.

Really appreciate any help you can lend on this!

Thanks and Happy New Year to all fellow virtual aviators!!
