The same problem I got a few days ago by our runtime applications.
I have added to the code the following statements.
Liam E. Gumley told me this code by one of my color questions in May.
device, true_color=24
window, /free, /pixmap, colors=-10
wdelete, !d.window
device, decomposed=0, retain=2
!p.background=255
!p.color=0
If this won't work please give a note again.
