Diablo III: Maximized Window Fix

I don't know if anyone else has this problem, but it was bugging the hell out of me, so I thought I'd share a solution I found.

The problem is this: Running Diablo III in windowed mode, but maximized. That is, you can still see the taskbar, but otherwise, the game is filling the remainder of the screen. This is how I play World of Warcraft, but Diablo 3 does not allow you to maximize in windowed mode. (WTF BLIZZARD)

So the first thing you will need to do is install a program called AutoHotkey. This part is pretty straight forward.

Next, you need to make a script that you will use to fix the window. To do this, open notepad and paste this:

^!f::
WinGetTitle, currentWindow, A
IfWinExist %currentWindow%
{
   WinSet, Style, -0xC00000 ; hide title bar
   WinSet, Style, -0x800000 ; hide thin-line border
   WinSet, Style, -0x400000 ; hide dialog frame
   WinSet, Style, -0x40000 ; hide thickframe/sizebox
   WinMove, , , 0, 0, 1920, 1040
}   
return

Note: Where you see "1920, 1040" in the script above is for a desktop resoluton of 1920x1080 on Windows 7 with large taskbar icons. These numbers will be different depending on your display resolution, windows version, and icon size. See additional info below.

Now save the file, (on the desktop is fine, or somewhere else if you want it out of sight) - it doesn't matter what you name it, but save it with a  ".ahk" extension. (Ex: "Fullscreen.ahk")

Once you've got the script created, right-click on it and Run as administrator. (If your windows account is an administrator, then just select Run Script.)

Now you're ready to open up Diablo III -  make sure you have it in windowed mode, and in focus - then press  Control+Alt+f and BAM! Maximized window mode. 

*Addition information on window size settings: The first number should always be the horizontal resolution of your display. The second number is going to be your vertical resolution minus the number of pixels needed to show the taskbar. In windows 7, large icons make the taskbar 40 pixels vs. 30 pixels for small icons. After some searching, I believe Vista and XP taskbars are 30 pixels as well.  

If subtracting either 30 or 40 pixels doesn't work for you, the best way to find out how many pixels to leave for your taskbar is to screencap your desktop (press printscreen to copy screen to the clipboard) and use an image editing program, like Photoshop, to crop out the taskbar. Once you've done that, the dimensions of the resulting image should tell you how many pixels you need to cut out. If all else fails, you could just guess, edit your script, run the script, test it, guess, edit, run, test, etc. till you find what works.
