Hey guys,
This will be a fairly long post since what I'm trying to achieve is pretty specific.

In a nutshell, I have two monitors running on Windows Vista. Using a program called Ultramon, I manage to get my one World of Warcraft window span the two monitors. The problem is that since the span is emulated, WoW does not offer me custom ultra-wide resolutions so there's an insane amount of stretching.

So, how can I run WoW at, in my case, 1360 x 450 in windowed mode? I tried changing the config.wtf file to reflect that, but it just resets to 800x600. Any other ideas?
