What this program does is what most people used Windower for.
Just change your video settings to whatever resolution you want to run it in (preferable your monitor resolution, but any resolution will work), and run it in Windowed mode. Once in-game, hit the "FFXIV Fullscreen" button, and it's done; you can close the fullscreener.
Does not interact in any way with the FFXIV game, all it does is send messages to the window containing FFXIV to resize/change parameters. This version also works with Wow, although mostly for testing purposes. (Wow already has an option to do the exact same thing) Newer versions will allow selecting any running process.
Please leave feedback. Expecting a few "don't trust 3rd party programs", and that's fine.
If you do try it, please post your OS/version, whether it works or not. I haven't done much programming lately, and 64/32 Windows API are not the friendliest waters to jump back into. Was written/tested on Windows7 x64, would like to hear from someone on 32-bit.
