Why does TCM sometimes show fewer or different colors?

This is probably caused by other programs that already run and which occupy too much entries in the X color map – leaving not enough for TCM. You are probably running in 8-bit (256 color) mode, and have other programs that use colors running on your display. Common culprits are background pictures or patterns, and Netscape, which is a notorious color hog. You can best start up TCM first because it takes only what it needs, and then start up Netscape and the other color eaters. Netscape can also be started with the options -install for using a private color map or with -ncols to set the maximum number of colors that it uses. When TCM cannot find any colors (on a color display) then it starts with a private color map. When you start TCM with the option -priv_cmap, it always uses a private color map. If you want to use TCM by default with a private colormap you can set the option PrivateColormap to True in the file TCM_CONFIG/tcm.conf or in $HOME/.tcmrc.
