Try this:
REM batch file to launch 2 evenly spaced wows
REM WOW1
c:\wow2\maximizer.exe --margin 512,0,0,0
REM WOW2
c:\wow3\maximizer.exe --margin 0,512,0,0
Also note: I have no idea why but I had to make 2 individual .bat files for each wow window instead of the above combined batch file.. you might not have to. could be a hardware issue for me.
