I'll give that a try today, see how it goes.
EDIT: Alright, tried with the newly downloaded TESV.exe, after removing the exe for the skyrim script extender, same thing occurred. Is it possible that the FXAA files I have that load when Skyrim loads are causing it? I was pretty certain those just have an affect on the final image displayed rather than messing about with Skyrim's process.
Well you may try without the file (if possible)s, anything may help now, please post back if you find the solution as it may help other users.
I wonder if the next SKYRIM update will again break the wide screen fix??
Also, I have been using .91 fix but not running it as an administrator and it is running fine? Is that normal?
Yes, it will probably break it, but HaYDeN should release a new version of the fix that will support v 1.4. Yes it normal, no problem.
