I am using IDL with OpenLook, but I've seen the same behavior. The fix is to call the routine "clear_colormap" immediately after exiting from X-windows. I ensure this by running X-windows from inside a shell script with the following line being "clear_colormap", i.e. #!/usr/bin/csh setenv IDL_DEVICE x setenv OPENWINHOME /usr/openwin $OPENWINHOME/bin/openwin -noauth $* clear_colormap Bill Thompson

I have experienced this. What is happening is that Wave is changing the colormap for the Sparc. The base Wave color table (B/W Linear) causes plots to be white lines on a black background. Unfortunately, this translates to white letters on a white background once you exit X. Doing a "clear_colormap" command, or reinvoking X will fix it. Alternatively, the last thing you can do before exiting Wave is to load a color table where the top value is black. The "prism" color table, number 6 I think, will do. |-Ian Novack (Particle Man)----------------------------ian@gomez.jpl.nasa.gov-| | "Don't worry about it.
