Errr... maybe this is vaguely relevant to my problem: idl colours under
linux; wanting to use 8-bit to get colour tables; set display appropriately.
Then under gnome/kde, colour tables don't work properly: I can use xloadct
to load new tables, but the tables don't show up in normal plot windows,
*unless* you hold the mouse over the graphics portion of a widget, whereupon
it works OK! OTOH, under windowmaker, all is fine (except for the inconveniences
of using windowmaker of course...).
