2005-10-01 Christian Persch <chpe@cvs.gnome.org> * lib/widgets/ephy-spinner.c: (ephy_spinner_init), (ephy_spinner_start), (ephy_spinner_stop), (ephy_spinner_map), (ephy_spinner_unmap), (ephy_spinner_class_init): Don't spin unmapped spinners. Slightly decrease the frequency. Might help with bug #315232.
