I got triple monitor working, but...

OK so I had 2 monitors going for a long time with nvidia's twinview, but I got a third monitor for free recently and figured I'd put it to use. I've got it all setup and working alright except for a few things. The viewsonic p810 and the sony trinitron 20se are hooked up to the first video card using nvidia's twinview. The viewsonic ps790 is hooked up to the second video card. Now here's where the problems start, I'm unable to drag windows between the viewsonic ps790 on the second card, and the 2 other monitors on the other video card. However, I can drag windows between the ones on the first card, so dragging a window from the p810 to the trinitron works. The other problem is now it seems that my window manager is unaware of the split between the 2 displays, so when I try to full screen a video on the trinitron, it tries to play it across both the p810 and the trinitron. Also maximized windows on either the trinitron or p810 will try to span both monitors. I suppose I could just change the way they're plugged in, so the trinitron is on the second card, since that's the one I always watch videos on, but I'd still like to have windows maximize correctly and cover only one display. The window manager I'm using is fvwm, and before when I had only the two monitors hooked up to the first video card, it always maximized correctly. Here's a copy of my xorg.conf file.

OK, after some of the reading there I added the Xinerama on option to the serverflags section, and now I can drag windows between all 3 displays. It still won't respect the screen differences between the two monitors on the first video card, but I've just swapped around the orientation so the monitor I watch videos on is on the second video card, this way at least videos only take up that display when full screened. Here's an updated xorg.conf in case it'd help anyone else setting up a triple monitor setup.
