Your already hit everything I would suspect. I know their were some vista fixes in 3.13 so hopefully it resovles it. As a mod we dont have any access to the graphical layer so I cant do much in FfH to resolve this.
Thanks for your reply, Kael.
I loaded the patch and .25 with patch g and it is still messed up.
It's very frustrating having to play the game in a window using a 22 inch widescreen monitor.

When I select the Full Screen mode, some screens work, but most do not. I am still getting that flickering. Yesterday, I tried 2 other video cards with the same result. It is just bizarre that more graphics-intensive games like Bioshock, Two Worlds, and Lost Planet play fine. I guess I will just have to wait until I return to Thailand next month and see how things go with my setup there.
I will say I played my first game (in a window) and found no real bugs. It was a short game, though. My Epic game ended in a Conquest victory for me in yr. 287. The barbs wiped out everyone but Charadon, who had a peace treaty with them. I managed to get a small stack of units out of my borders and took down the Doviello. I was getting stacks of barbs every turn attacking my two Elohim cities. I would like to say the result was because of better barb AI, but again, I think it is just poor civ AI who cannot seem to adjust to the raging barbs and focuses on expansion rather than defense.
I did notice I failed to get a Thane when I founded ROK, but it wasn't a big deal because it spread to my only other city, my capital, it about 10 turns just before I built a Thane after the Temple of Kilmorph was built.
You and your team truly amaze me how you keep raising the bar and making this mod better and better. I honestly cannot remember enjoying a pc game more than CIV/FFH2....even though I have to play it in a window!
