Multimonitor clicking and dragging issues

Hello,

I have two nvidia cards, three monitor setup. Removed unity, installed gnome-panel. I try clicking and dragging in nautilus, but when I drag, the icon moves immediately to the monitor to the left. Same coordinates, but just snaps to one monitor over.

Multimonitor is configured as separate X screen + Xinerama.

Any ideas?

Thanks!

Still having this problem, not sure what is going on. Sometimes if I click and drag on a window, the window will snap one desktop over as well.

Confirmed this happens in fluxbox, so it's not a window manager problem, I'm guessing it's a problem with X.

Any ideas?
