For anyone else besides me who has a 16:10 setup running 3360x1050, heres a batch file to 5box using wow maximizer. I saw this on the wiki and just changed the math to meet my resolution.

[code:1]REM batch file to launch 5 evenly spaced wows
REM Left monitor
D:\wow1\maximizer.exe --margin 0,0,0,1680
REM upper right of right mon
D:\wow2\maximizer.exe --margin 0,525,2520,0
REM upper left of right mon
D:\wow3\maximizer.exe --margin 0,525,1680,840
REM lower right of right mon
D:\wow4\maximizer.exe --margin 525,0,2520,0
REM lower left of right mon
D:\wow5\maximizer.exe --margin 525,0,1680,840 [/code:1]

copy and paste into notepad , change directories as needed, save as .bat file.
