This reply isn't going to be much help, but I don't use the DX10 preview mode so I have no real advice to offer. But from your description you are failing on a simple step. Are you sure you have the batch file in the right place and that you are specifying the path correctly? And there are no syntax errors in the file? Is there not a forum where the fixer is discussed and supported?
Thanks for the answer Mark, ve been very busy but tried p3d and definitely its not for me. The lack of official support for 2d panels is there and is followin the trend of many single monitor simmers that are contempt with ezydok.
As far as the bat file im sure im doing it correctly and it is placed on fsx´s installation folder.
Ive tried both for the boxed and steam version.
Il guess dx9 will have to do.
Hopefully dovetal flight sim doesnt disregard multimonitor simmers and the addons quickly start catching up for this sim.
