Rose,

Please try the following:

1. If you are sitting at the SGI console, logout, then log back in.

2. Start a new IDL session, and enter the following:
print, !d.n_colors, !d.table_size
device, true=24, decomposed=0, retain=2
window, /free, /pixmap
wdelete, !d.window
print, !d.n_colors, !d.table_size

3. Try displaying a couple of GIFS using this method:
read_gif, './GIF_FILES/test1.gif', image, r, g, b
tvlct, r, g, b
window, /free
tv, image ; NO BYTSCL!

Please let us know if it works.

Cheers,
Liam.
