You can pre-set the colors idl uses in .Xdefaults, I believe. Also, Gnome
is a desktop environment, not a window manager, last time I installed it.
You must be using Enlightenment or BlackBox maybe? I use Gnome / Enlightement
currently (with IDL), I used to have to put a few lines like:
#idl.colors: 16777216 <------ note this is commented out!
in .Xdefaults to get color working in X w/idl (that was using AfterStep wm).
Most important is idl.retain, which tells IDL to handle the window's backing
-store, instead of the window manager. You may want to try that.
