Comment 14 for bug 455378

It seems that others have had success working around this bug, but I have to confess that I am at a loss... With compiz enabled, I cannot drag-resize windows to larger than one screen. Neither can I make full-screen of an application use up multiple screens... this is especially problematic with VNC where I need to control systems with multiple monitors. Can anyone help with straightforward instructions to enable the functionality that I need with compiz enabled?
