cluster-ssh with multiple monitors

I have 3 monitors, one big and two small. When I start cssh, the xterm windows cover all 3 monitors. That would be fine, if the xterm windows did not overlap the monitor boundaries. But unfortunately, what I get is basically xterm window where one half is on monitor 1 and the other half on monitor 2. I would like to restrict cssh to only use one monitor. I am using openbox window manager, and I tried adding the following to my xml config: yes yes 2 Using the xml config, I can change details such as `, but 2` has no effect. Is there a way to tell cssh to only use monitor 2 ?
