1302 xtdpy =3D XtOpenDisplay(app_con, NULL, "r_x11",=20 "R_x11", 1303 NULL, 0, &zero, NULL); 1304 toplevel =3D XtAppCreateShell(NULL, "R_x11", The 2nd arg to XtOpenDisplay is listed as display_string, so passing a=20 NULL here seems like trouble when the default ways of finding the=20 display do not work. Looks like a fix is to insert p instead of NULL. (Tested rudimentarily.) --=20 O__ ---- Peter Dalgaard =D8ster Farimagsgade 5, Entr.B c/ /'_ --- Dept. of Biostatistics PO Box 2099, 1014 Cph.
