Weird Maximizer Problem with 2 screens

Hey,

So I've read the tutorials here and came across a weird problem. I've no idea how to solve it and maybe you guys could help me out.

I have a 8800 GTS 320MB and I've set my view to span view. Both screens are 19" with a 1280x1024 resolution. I run Windows XP.

My bat file:
[code:1]
REM Left monitor
E:\Blizzard\wow\maximizer.exe --margin 0,0,0,1280 -R 2560x1024
REM Right monitor
E:\wow2\maximizer.exe --margin 0,0,1280,0 -R 2560x1024[/code:1]

Now when I doubleclick it, the first WoW window starts and places itself on the left screen. Right. Works perfectly fine.
However the other instance just doesn't want to start until I close the first instance.

I've tried using this:
[code:1]REM batch file to launch 2 wows
REM Left monitor
E:\Blizzard\wow\maximizer.exe --margin 0,0,0,1280
REM Right monitor
E:\wow2\maximizer.exe --margin 0,0,1280,0 [/code:1]
Then both instances start, the first one looks great and is on the left screen as it should be - the other one however is very small, frozen and on the top left corner of the right monitor.
Again, if I close the first instance, the second one maximizes and places itself on the right monitor.

What I did is, I went back to dual-view this batfile:
[code:1]REM batch file to launch 2 wows
REM Left monitor
E:\Blizzard\wow\maximizer.exe --margin 0,0,0,0
REM top of right mon
E:\wow2\maximizer.exe --margin 0,0,1280,0[/code:1]
Both instances work, none are frozen (cursor blinks on the second one). However the second instance on the right monitor is strechted down to like 1/16th of the screen. I cannot make it full sized.

Any idea what I could do? I tried dual-view with --device 1 and 2 but then the second instance is frozen and the first one lags like hell. :'(
