disable horizontal resize of window?

    Nov 20 2011 | 6:44 am
    i'm thinking about a way to only allow vertical window resizing + vertical scrollbar only.
    i do not want to constantly send getwindow size to [thispatcher] to detect user trying to resize horizontal.
    nogrow (to thispatcher) disables both, hor/ver resizing, and it seems to disable scrollbars completely
    can you help with some ideas?
