24 bit displays, private colormaps, and other things that keep my up [message #9904]

I don't mind the color flashing that results from a private colormap
using IDL/X windows, my problem is this: Why don't widgets use the same
colormap as the rest of IDL? In 8-bit pseudo-color mode (on my 24-bit
fvwm-managed X display), I can display an image using:

window
tvscl,image

and get the correct image colors only when I have the mouse on the image
(fine, I can deal with that). If I create a widget using:

base=widget_base()
draw=widget_draw(base)
widget_control,base,/realize
widget_control,draw,get_value=drawID
wset,drawID
tvscl,image

I get the wrong colormap, same as before, but if I put my mouse on the
widget, I don't get back the correct colormap. Like I said, I don't mind
the flashing, but does anyone know how to make sure that *all* IDL
windows use the same colormap?

Frustrated,
