Fri Mar 12 10:53:10 1999 Owen Taylor <otaylor@redhat.com> * capplets/theme-switcher/main.c (main): Wait for our child to exit before quitting. The prevents us from pulling the socket window out from under our child. * capplets/theme-switcher/demo.c (demo_main): Clean up some warnings about types in formats. * capplets/theme-switcher/demo.c (demo_main): Exit cleanly if read from parent fails - don't drop a core.
