so spewing i realised on the first day that "sharing" would not open in the preferences panel. so i ignored it for a coupla days, then eventually on the 8th day tried a restart to see if it would fix it. but it didnt. so i reinstalled leopard last night (archive and install) and everything works perfectly and faster than before. startup times have more than halved so yea. i wonder what went wrong??? has anyone else had this or another problem like it?
